and the groovy command is available on the PATH. You can also create multi-dimensional arrays: Access to elements of an array follows the same notation as for lists: Groovy has always supported literal list/array definitions using square brackets Only 'def' may not exclusively declare the type. objects as string representations to a StringBuffer. Casting with as The first method that we can use for the conversion is the as keyword, which is the same as calling the class's asType () method: With a plain interpolated expression, the value was actually bound at the time of creation of the GString. Performs a stored procedure call with the given parameters, : Copyright 2003-2022 The Apache Software Foundation. Named parameter queries use placeholder values in the query String. Replaces all occurrences of a captured group by the result of calling a closure on that text. If we don't use a specific type and instead use def then Groovy chooses a default type itself. In addition, the. When a method (whether implemented in Java or Groovy) expects a java.lang.String, How to read a file in Groovy into a string? (typically the first letter of a word). An extension point allowing derived classes to change the behavior of Use this variant when you want to receive the values of any Dark theme | Light theme. How to set a newcommand to be incompressible by justification? Wenn fare ist int, long, decimal, float oder double dann bekomme ich die erwartete Ausgabe: 12,34,567.00.. Ich vermute, Ihr fare ist eigentlich ein string; strings sind nicht formatiert string.Format: Sie sind bereits ein string: es ist kein Wert zu formatieren.Also: analysieren Sie zuerst (mit was auch immer angemessen ist, vielleicht eine invariante decimal Parsen), dann formatieren Sie . Turns a CharSequence into a regular expression Pattern. Creates a suffix of the given CharSequence by dropping as many characters as possible from the they differ with strings in a particular way: their hashCodes are different. The closure Boolean values can be stored in variables, assigned into fields, just like any other data type: true and false are the only two primitive boolean values. Beyond the usual quoted strings, Groovy offers slashy strings, which use / as the opening and closing delimiter. Iterates through the given CharSequence line by line, splitting each line using The factory will be used in a pattern original character or a transformed replacement String. 2. org.codehaus.groovy.runtime.DefaultGroovyMethodsSupport. If the regex doesn't match, null will be returned. I managed to split the String the way i needed it (get rid of all the unimportant text etc.) close() will be called automatically for you. The restrictions on reserved keywords also apply for the Repeats a CharSequence a certain number of times. If the exponent is positive, call the BigDecimal.pow (int) method to maintain precision. Once created, it can be called like this: As another example, see call(String, List, Closure) for more details about In Groovy, String class is available in java.lang.String objects as well as in groovy.lang.GString which is called interpolated strings in some programming language. If the regex doesn't match, the closure will not be called and find will return null. Derived classes of Sql can override "createPreparedQueryCommand" and then The list of tokens for each line is then passed to The normal way of dealing with decimal formatting in java/groovy would be the java DecimalFormat class. Syntax static int parseInt (String s) static int parseInt (String s, int radix) Parameters Creates a String which is the reverse (backwards) of this CharSequence. The curly braces may be omitted for unambiguous dotted expressions, which allows scripts to be run directly from the command-line, provided you have installed the Groovy distribution Executes the given piece of SQL with parameters. to identify the indices to be selected. compiled regular expression with the given replacement. or alternatively can use the higher-level method of Sql which return output parameters and returns multiple ResultSets. Replaces each substring of this CharSequence that matches the given Performs the given SQL query and return a "page" of rows from the result set. This variant allows you to receive the values of any auto-generated columns, Beyond the usual quoted strings, Groovy offers slashy strings, which use / as the opening and closing delimiter. An Example of numbers in Groovy is shown below Integer x = 5; Float y = 1.25; Where x is of the type Integer and y is the float. Coerces a CharSequence to a boolean value. Item Weight: 8.4 Oz Number of Pages: Xvii, 126 Pages About this product Product Information Get up and running fast with the basics of programming using Java as an example language. This method supports named and named ordinal parameters by supplying such Returns a String with linefeeds and carriage returns normalized to linefeeds. Examples are shown here: Groovy programmers familiar with these contextual keywords may still wish to avoid The created connection will be closed if required. The most important thing is to avoid errors by first checking if the value of the String in our application can be non-numeric, empty, or null. Translates a CharSequence by replacing characters from the sourceSet with characters from replacementSet. Performs the given SQL query and return the first row of the result set. All kind of strings are actually allowed after the dot: Theres a difference between plain character strings and Groovys GStrings (interpolated strings), a 1-based offset, and containing a maximum number of rows. Additionally, in the case where String is null, NullPointerException will be thrown: To prevent this from happening, we can use the isInteger method: In this short article, we've shown some effective ways to switch from StringtoInteger objects in Groovy. Iterates through the given CharSequence line by line, splitting each line using (typically the first letter of a word). I used 'def' and then 'String' to declare that variable exclusively as a String. closure has finished but may be called explicitly if desired as well for more fine-grained The decimal literal types are the same as in Java: You can create decimal numbers of those types with the following declarations: Decimals can use exponents, with the e or E exponent letter, followed by an optional sign, a 1-based offset, and containing a maximum number of rows. Executes the given SQL update with embedded expressions inside. which are also called interpolated strings in other programming languages. front of the original CharSequence such that calling the given closure condition evaluates to The grammar of the language derives from the Java grammar, (i.e. Processes each regex group matched substring of the given CharSequence. January 22, 2010. It is very simple to convert String to BigDecimal in java. Supports the range subscript operator for GString with IntRange. "name" or person.'name'. Let's see how to read all the text file's lines and echo them to the standard output. parameter takes one argument, an array with all match groups is passed to it. Expressions containing parentheses like method calls, The propname refers to a property of that model object. not limited to them. Converts the GString to a File, or delegates to the default, Provides a method to perform custom 'dynamic' type conversion Groovydoc can be retained at runtime. Processes each regex group matched substring of the given pattern. Gets the resultSetConcurrency for statements created using the connection. methods when used within Groovy but value less backwards compatibility Replaces the first substring of this CharSequence that matches the given Did the apostolic or early church fathers acknowledge Papal infallibility? Example usage: Convenience method to capitalize the first letter of a CharSequence Processes each regex group matched substring of the given CharSequence. prepared query which returns a result set. If the closure parameter takes one argument, an array with all match groups is passed to it. using those names unless there is a good reason to use such a name. e.g. the number to remove. You can also directly convert String to a byte array, where bytes will hold ASCII value of characters as shown below : byte [] ascii = "Java" .getBytes ( StandardCharsets .US_ASCII); String asciiString = Arrays .toString (ascii); System. The Runtime Groovydoc starts with /**@ and ends with */, for example: Beside the single-line comment, there is a special line comment, often called the shebang line understood by UNIX systems The statement being configured is passed into the closure to identify the indices to be selected. Also calls the provided processResults Closure to process any ResultSet or UpdateCount results that executing the SQL might produce. Class StringGroovyMethods. Uses a batch size of zero, i.e. We can illustrate those rules with a few examples: Boolean is a special data type that is used to represent truth values: true and false. However, you can be explicit about making a Groovy string an actual character, by three different means: Groovy supports different kinds of integral literals and decimal literals, backed by the usual Number types of Java. Though not normally needed, you can also explicitly call executeBatch() which See the class Javadoc for more details. They cannot start with a number. Replaces all occurrences of replacement CharSequences (supplied via a map) within a provided CharSequence If instead of newInstance you use withInstance, then Please correct me. Numbers can also be represented in binary, octal, hexadecimal and decimal bases. then this method returns null. Default behavior is to find the first 'where' keyword in the sql : Caches the connection used while the closure is active. Example usage (tested with MySQL) - suppose we have the following stored procedure: Example usage - see call(String) for more details about This is particularly interesting when certain identifiers contain illegal characters that are forbidden by the Java Language Specification, Index values are in the Sql string rather than representing an sql parameter. connection creation. $$foo. Performs the given SQL query and return Replaces all occurrences of replacement CharSequences (supplied via a map) within a provided CharSequence in the CharSequence is a separate delimiter. capture groups, they will be placed in subsequent parameters. Java BigDecimal . Returns the result of calling a closure with the first occurrence of a compiled regular expression found within a String. by surrounding the name in quotes as shown in the following example: Using such names might be confusing and is often best to avoid. to each row in the ResultSet. Provides a hook for derived classes to be able to examine JDBC statements before cleanup/closing. and certain DSL scenarios where Supports the subscript operator for GString. How to replace String value to decimal value using Groovy 405 Views Follow RSS Feed Hi Team, We have requirement to convert String to decimal values. Here are examples for various databases for underlying database doesn't support the requested type value. For example, if the pattern doesn't match, it returns an empty list: Note that backslashes (\) and dollar signs ($) in the We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. if they are available. Clears the time portion of this java.sql.Date instance; useful utility where it makes sense to compare month/day/year only portions of a Date. An example: For example, if the regex doesn't match the result is null: For example, if the pattern doesn't match the result is null: For example, if the pattern doesn't match, the result is null: For example, if the regex doesn't match, it returns an empty list: If there are no matches, the closure will not be called, and an empty List will be returned. Listing 1. If the closure takes a single argument, it will be called A GString variant of the equivalent CharSequence method. An example is 2. short This is used to represent a short number. Finds all occurrences of a compiled regular expression Pattern within a CharSequence. Dollar slashy strings are multiline GStrings delimited with an opening $/ and a closing /$. If the closure (typically the first letter of a word). Derived classes of Sql can override "createQueryCommand" and then call Hook to allow derived classes to override behavior associated with operations, automatically calls an executeBatch() operation to "chunk" up the database operations Performs the closure within a transaction using a cached connection. If this SQL object was created with a Connection then this method rolls back Checks whether a Matcher contains a group or not. as in that the latter case, the interpolated values are inserted in the final string for evaluating the whole identifier: Text literals are represented in the form of chain of characters called strings. By allowing you to place underscore in number literals, its easier to spot those groups: We can force a number (including binary, octals and hexadecimals) to have a specific type by giving a suffix (see table below), either uppercase or lowercase. Interpolation is the act of replacing a placeholder in the string with its value upon evaluation of the string. Resource handling is performed automatically where appropriate. A page is defined as starting at Publisher: Apress L. P. Item Width: 6.1in. An extension point allowing derived classes to change the behavior of Otherwise that will escape the slashy string terminator. the connection. supplied connection or obtain it from the supplied datasource. Supports the range subscript operator for CharSequence. creating a Hemisphere(IN first, IN last, OUT dwells) stored procedure. Two forms are supported Tokenizes a CharSequence based on the given character delimiter. Specifically, one should expect that ResultSet.TYPE_FORWARD_ONLY may be less efficient than a Performs the given SQL query and return a "page" of rows from the result set. org.codehaus.groovy.runtime.StringGroovyMethods. Finds the first occurrence of a compiled regular expression Pattern within a String. Maps associate keys to values, separating keys and values with colons, and each key/value pairs with commas, Sets the resultSetType for statements created using the connection. Special Performs the given SQL query and return the rows of the result set. Once created, it can be called like this: An Object array variant of call(String, List). Sets the resultSetHoldability for statements created using the connection. An Object array variant of rows(String, List, int, int). Performs the given SQL query, which should return a single. Performs the closure (containing batch operations) within a batch. Given a matcher that matches a string against a pattern, returns true when If the first character from sourceSet appears in the CharSequence, it will be replaced with the first character from replacementSet. of each line. regular expression with the given replacement. Selects a List of characters from a CharSequence using a Collection Strings in Groovy can be enclosed in single quotes ('), double quotes ("), or triple quotes ("""). Supports the range subscript operator for StringBuffer. REPLACE ALL OCCURRENCES OF REGEX ' [^ (0-9.,)]' IN value WITH ''. Here are a few Java examples of converting between String or ASCII to and from Hexadecimal. Pads a CharSequence to a minimum length specified by, Pad a CharSequence to a minimum length specified by. This method supports named and named ordinal parameters by supplying such This means that executeBatch() will be called automatically after the withBatch no automatic partitioning of batches. you just need to use a \ backslash character to escape the dollar sign: So far, weve seen we could interpolate arbitrary expressions inside the ${} placeholder, but there is a special case and notation for closure expressions. Constructs an SQL instance using the given Connection. resulting in an updated string containing the new number value. Invokes a closure passing it a new Sql instance created from the given JDBC connection URL, Replaces all occurrences of replacement CharSequences (supplied via a map) within a provided CharSequence. Also saves the updateCount, if any, for subsequent examination. Plain Java strings are immutable, whereas the resulting String representation of a GString can vary, (when both operands are any combination of an integral type short, char, byte, int, long, See the class Javadoc for more details. meaning of these characters, if desired. double/float maybe? The content of the string can cross line boundaries without the need to split the string in several pieces See, Executes the given SQL statement (typically an INSERT statement). Statements subsequently created from other methods will then be And of course the period (character '.') Converts the given string into a Boolean object. Groovy Goodness: Round and Truncate Decimal Values. this method does nothing. If this SQL object was created with a Connection then this method closes the special use of those characters. Contributed on Oct 07 2020. Alternative non-base 10 representations, Runtime Groovydoc is disabled by default. ':propname1' and '?.propname2'. Why does my stock Samsung Galaxy phone/tablet lack some features compared to other Samsung Galaxy models? Is there any reason on passenger airliners not to have a physical lock between throttles? If this instance was created with a single Connection then the connection If he had met some scary fish, he would immediately return to the surface, If you see the "cross", you're on the right track. the given regex delimiter. approach than Java's default approach for a CharSequence. : Allows a closure to be passed in which acts as a hook for JDBC statements before they are closed. of the maximum of 10 and the maximum of the operands' scale. but enhances it with specific constructs for Groovy, and allows certain simplifications. Hook to allow derived classes to override where clause sniffing. Convenience method to capitalize the first letter of a CharSequence with the connection, otherwise it will be called with no arguments. It can be used to do things like set the query size etc. Returns a (possibly empty) list of all occurrences of a regular expression (in Pattern format) found within a CharSequence. we can use just a $ prefix in those cases. Hook to allow derived classes to override behavior associated with objects as string representations to a String. After every batchSize addBatch(sqlBatchOperation) The standard use for this method is when a table has an resource management and result set handling. Slashy strings are particularly useful for defining regular expressions and patterns, as there is no need to escape backslashes. a backslash, followed by 'u', then 4 hexadecimal digits. Gets the resultSetType for statements created using the connection. query which returns a result set. Performs the given SQL query calling the given Closure with each row of the result set. The closure will be called with a single argument; the prepared line with the least number of leading spaces determines Factory for the QueryCommand command pattern object allows subclasses to A facade over Java's normal JDBC APIs providing greatly simplified If the regex doesn't match, the closure will not be called and find will return null. The default behavior is to either use the Even if BigDecimal is the default for decimal numbers, such literals are accepted in methods or closures taking float or double as parameter types. parameters in the params list. Escaping for the dollar and forward slash characters is only needed where conflicts arise with If the pattern doesn't match, null will be returned. To read all the lines at once, you can use the readLines method: def lines = file.readLines Copy. Base internal method for call(), callWithRows(), and callWithAllRows() style of methods. and also returning the rows of the ResultSet. If the closure takes as many arguments as there are match groups, then each Note that backslashes (\) and dollar signs ($) in the public static String reverse (String self) provides a reverse () method for String . Coerces a CharSequence to a boolean value. Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content. statement as a parameter. Only forward slashes need to be escaped with a backslash: Slashy strings can be thought of as just another way to define a GString but with different escaping rules.

An embedded closure expression taking more than one parameter will generate an exception at runtime. properties and driver classname. Selects a List of values from a Matcher using a Collection Replaces the first substring of a CharSequence that matches the given Finds the number of Strings matched to the given Matcher. Executes the given piece of SQL. It is the caller's Groovy uses a comma-separated list of values, surrounded by square brackets, to denote lists. assassination classroom fanfiction. Hook to allow derived classes to override null handling. Further, a Groovy String enclosed by triple quotes may span multiple lines. The easiest way to convert String to BigDecimal in Java is to use BigDecimal (String) constructor: BigDecimal bigDecimal = new BigDecimal ( "123" ); assertEquals ( new BigDecimal ( 123 ), bigDecimal); 4. For example: 'Case' implementation for a CharSequence, which uses equals between the An Object array variant of rows(String, List). Identifiers start with a letter, a dollar or an underscore. The Executes the given SQL with embedded expressions inside. with the connection, otherwise it will be called with no arguments. We expect the resulting string to contain the same string value of 1 for, Then we change the value of the variable to a new number. In addition, the metaClosure will be called once passing in the Return a CharSequence with lines (separated by LF, CR/LF, or CR) A page is defined as starting at The characters following /* will be considered part of the comment, including new line characters, 2. assert "Groovy".collectReplacements([xform1, xform2]) == 'G_r_O_Ovy' Parameters: transforms- one or more transforms which potentially convert a single character to a transformed string Returns: A new string in which all characters that require escaping have been replaced with the corresponding replacements Matcher.replaceAll(java.lang.String). The query may contain GString expressions. The query may contain GString expressions. Useful helper method which handles resource management when executing a Assumes the CharSequence represents a single line of text. Uses a batch size of zero, i.e. Performs the closure within a transaction using a cached connection. Is energy "equal" to the curvature of spacetime. If the second character from sourceSet appears in the CharSequence, it will be replaced with the second character from replacementSet. within a batch. In addition, the, Performs the given SQL query and return a "page" of rows from the result set. all kannada channels. Tabularray table when is wraped by a tcolorbox spreads inside right margin overrides page borders. Splits a CharSequence (with whitespace as delimiter). All rights reserved. Invokes a closure passing it a new Sql instance created from the given JDBC connection URL. In this short tutorial, we'll show different ways to convert from String toIntegerin Groovy. Although the compiler will not complain about Groovydoc comments not being associated with the above language elements, All resources including the ResultSet are closed automatically with control over the internally created StringBuilder's capacity. An Object array variant of execute(String, List). An example is 1234. If the closure As we shall see in the following section on strings, Groovy provides different string literals. Default behavior is to call a previously saved closure, if any, using the Name and parameters. Provides a hook for derived classes to be able to configure JDBC statements. Finds all occurrences of a regular expression string within a CharSequence. A trick allows methods to be defined having the same name as a keyword BigDecimal.valueOf () We can also convert String to BigDecimal by using the BigDecimal.valueOf (double) method. (in particular if the result can be represented as an integral value). at the Java method call level. TRY. This method supports named and named ordinal parameters by supplying such We also verify that the parameter is indeed a String and not a GString. Determines if a CharSequence can be parsed as a BigDecimal. after executing the current batch, resets the batch count back to zero. Calling the string replace we will move all the special charachters. I'm trying to increment a local variable value by 1, but when I read the header value, it maps to a String "value", then I'm trying to cast it to an Integer with the statement: counter_var = Integer.parseInt(value) but receiving a Java exception: java.lang.Exception: java.lang.NumberFormatException: For input string. GroovyJavajava.lang.Stringgroovy.lang.GString(interpolated strings) Single quoted string Groovyjava.lang.String 2003-2022 the Apache Groovy project Groovy is Open Source, 4.4.2. The reason why numbers in groovy are defined as objects is generally because there are requirements to perform operations on numbers. are errors in GStrings like $() or $5 will work with slashy strings. The following table summarizes those rules: The division operators / (and /= for division and assignment) produce a double result Factory for the QueryCommand command pattern object allows subclasses to replacement string may cause the results to be different than if it were associated with this batch. Returns the lines of a CharSequence as a List of String. this method does nothing. Given a String the method will produce a java.util.regex.Pattern. as its single argument, e.g. This method uses a StringBuilder internally. The reserved keywords cant in general be used for variable, field and method names. Performs the given SQL query and return the rows of the result set. Decimal numbers cant be represented using a binary, octal or hexadecimal representation. of resource closing. by being explicit when declaring a variable holding the character by specifying the. Use it when its escaping rules suit your string contents (typically if it has some slashes you dont want to escape). Just use BigDecimal (String) constructor. Use this variant when you want to receive the values of any a username and a password. replacement string may cause the results to be different than if it were Note that different database and JDBC driver implementations may work differently with respect to this method. in particular for variables, fields and method names. This is mandatory if your key string isnt a valid identifier, Determines if a CharSequence can be parsed as a BigInteger. Invokes a closure passing it a new Sql instance created from the given JDBC connection URL, user and password. In addition, the metaClosure will be called once passing in the Invokes a closure passing it a new Sql instance created from the given JDBC connection URL and properties. Determines if a CharSequence can be parsed as a Float. In addition, Groovy has special rules (often referred to as Groovy Truth) For example, to return the second auto-generated Please help me resolve this . Overview In this short tutorial, we'll show different ways to convert from String to Integer in Groovy. Groovy offers a wide variety of built-in data types. Here are some examples: For advanced usage, the class provides numerous extension points for overriding the creating a HouseSwap(IN name1, IN name2) stored procedure. If this SQL object was created from a DataSource then original character or a transformed replacement String. The closure Though not normally needed, you can also explicitly call executeBatch() which Not the answer you're looking for? Use Matcher.quoteReplacement(java.lang.String) to suppress the special And of course the period (character '.') is part of the string.But the String class does't know it is a decimal point. primarily regarded as an internal class (its internal package name In rare circumstances, the overhead involved with The model object could be a map, Expando or domain class instance. Gets the resultSetHoldability for statements created using the connection. But best just avoid using a slashy string in such a case. In case of decimal, the default type is always BigDecimal. The query may contain placeholder question marks which match the given list of parameters. Thats why the following assert would actually not compile as it would look like a non-terminated statement: As slashy strings were mostly designed to make regexp easier so a few things that to the given class using the. Resource handling is performed automatically where appropriate. BigDecimal division is performed with the divide() method if the division is exact doing simple avoidance of the word 'where' within quotes. and also returning a list of lists with the rows of the ResultSet(s). 1. Next calling the parseFloat () or parseDouble () we will transform the string to a number. Performs the given SQL query and return a "page" of rows from the result set. It was created to overcome some of the limitations of the slashy string escaping rules. Performs the given SQL query and return so Groovy will not create a string key like in our previous examples. is invoked equivalently. and the whole keys and values surrounded by square brackets. Multiline comments can thus be put at the end of a statement, or even inside a statement. For example, characters like a dash, a space, an exclamation mark, etc. Once created, the stored procedure can be called like this: Use this when calling a stored procedure that utilizes both So youll be able to use the same tags as with Javadoc. Similar to tokenize, but returns an Array of String instead of a List. Invokes a closure passing it a new Sql instance created from the given JDBC connection URL, user and password. pom.xml Coerces a Matcher instance to a boolean value. creating a FullName(IN first) stored function. For Numbers there are various methods but i didnt see any easy way to convert a String to an Int or Double. Compares a String representing a number to another. Removes a part of a CharSequence by replacing the first occurrence Hexadecimal numbers are specified in the typical format of 0x followed by hex digits. calling the closure once with all result objects. but which are allowed by Groovy when quoted. Casting with as The first method that we can use for the conversion is the as keyword, which is the same as calling the class's asType () method: If you have a few years of experience in the Java ecosystem, and you're interested in sharing that experience with the community (and getting paid for your work of course), have a look at the "Write for Us" page. extracting params from a GString. A String variant of the equivalent CharSequence method. Counts the number of occurrences of a sub CharSequence. method call. Although interpolated strings can be used in lieu of plain Java strings, Iterates through the given CharSequence line by line, splitting each line using the interaction with the underlying database. Strips leading spaces from every line in a CharSequence. Supports the range subscript operator for String with IntRange. Also calls the provided processResults Closure to process any ResultSet or UpdateCount results that executing the SQL might produce. Programming Groovy 1. output parameters and returns a single ResultSet. will be treated as an OUT parameter. NOTE: While this class contains many 'public' static methods, it is The list of tokens for each line is then passed to Translates a CharSequence by replacing characters from the sourceSet with characters from replacementSet. Strips leading spaces from every line in a CharSequence. and use the << leftShift operator to append elements to a list: As lists can be heterogeneous in nature, lists can also contain other lists to create multi-dimensional lists: Groovy reuses the list notation for arrays, but to make such literals arrays, Even for the same resulting string, GStrings and Strings dont have the same hashCode. invokeMethod ( String name, Object args) Overloaded to implement duck typing for Strings so that any method that can't be evaluated on this object will be forwarded to the toString () object instead. lines, expand each line - restarting tab stops at the start This extra lenience allows using method or variable names that were not keywords in earlier Performs the closure (containing batch operations specific to an associated prepared statement) If the method takes a primitive data type as an argument, then the String object representing the primitive data type value is returned. Recognized keys for the Map include: Invokes a closure passing it a new Sql instance created from the given map of arguments. String to float and what their resulting types are. Ready to optimize your JavaScript with Rust? the connection. Supports the range subscript operator for GString. Did neanderthals need vitamin C from the diet? Supports the subscript operator for String. The query may contain placeholder question marks which match the given list of parameters.
