[Java] Class DefaultGroovyMethods

public class DefaultGroovyMethods
extends DefaultGroovyMethodsSupport

This class defines new groovy methods which appear on normal JDK classes inside the Groovy environment. Static methods are used with the first parameter being the destination class, i.e. public static String reverse(String self) provides a reverse() method for String.

NOTE: While this class contains many 'public' static methods, it is primarily regarded as an internal class (its internal package name suggests this also). We value backwards compatibility of these methods when used within Groovy but value less backwards compatibility at the Java method call level. I.e. future versions of Groovy may remove or move a method call in this file but would normally aim to keep the method available from within Groovy.
