Class Summary
Class | Description

Eval | Allow easy integration from Groovy into Java through convenience methods.
Expando | Represents a dynamically expandable bean.
FactoryBuilderSupport | Mix of BuilderSupport and SwingBuilder's factory support.
GroovyCollections | A Collections utility class
GroovyLog | Deprecated
GroovyMBean | A GroovyObject facade for an underlying MBean which acts like a normal groovy object but which is actually implemented via an underlying JMX MBean.
GroovyScriptEngine | Specific script engine able to reload modified scripts as well as dealing properly with dependent scripts.
GroovyTestCase | A default JUnit TestCase in Groovy.
GroovyTestSuite | A TestSuite which will run a Groovy unit test case inside any Java IDE either as a unit test case or as an application.

OrderBy<T> | A helper class for sorting objects via a closure to return the field or operation on which to sort.
PermutationGenerator<E> | Systematically generate permutations.
Proxy | Dynamic groovy proxy for another object.
ProxyGenerator | Classes to generate 'Proxy' objects which implement interfaces, maps of closures and/or extend classes/delegates.
XmlNodePrinter | Prints a `groovy.util.Node` (as used with `XmlParser`) including all children in XML format.
XmlParser | A helper class for parsing XML into a tree of Node instances for a simple way of processing XML.
