Groovy 1.6.5

Package groovy.lang

Core Groovy language classes for implementing data structures, closures, metadata and so forth.


Interface Summary
AdaptingMetaClass An interface for MetaClass instances that "adapt" other MetaClass instances such as a proxy or delegating MetaClass.
ClosureInvokingMethod An interface for MetaMethods that invoke closures to implements.
ExpandoMetaClass.Callable For simulating closures in Java
GroovyInterceptable Marker interface used to notify that all methods should be intercepted through the invokeMethod mechanism of GroovyObject.
GroovyObject The interface implemented by all Groovy objects.
GroovyResourceLoader Allows frameworks that integrate with Groovy to determine how Groovy files are resolved.
Interceptor Implementers of this interface can be registered in the ProxyMetaClass for notifications about method calls for objects managed by the ProxyMetaClass.
MetaClass A MetaClass within Groovy defines the behaviour of any given Groovy or Java class.
MetaClassRegistry A MetaClassRegistry is an object that is responsible for managing the a cache of MetaClass instances.
MetaClassRegistryChangeEventListener A listener called whenever a constant MetaClass is set, removed or replaced.

An interface that defines the API usable by clients of Groovy's Meta Object Protocol (MOP).


An interface that defines methods that implementors of mutable Meta classes should specifiy.


An interface that adds the ability to intercept property getters/setters

Range A Range represents the list of all items obtained by starting from a from value and calling next() successively until you reach the to value.
Writable Represents an object which is capable of writing itself to a text stream in a more efficient format than just creating a toString() representation of itself.

Class Summary
BenchmarkInterceptor Interceptor that registers the timestamp of each method call before and after invocation.
Binding Represents the variable bindings of a script which can be altered from outside the script object or created outside of a script and passed into it.
Closure Represents any closure object in Groovy.
Closure.WritableClosure Implementation note: This has to be an inner class!
EmptyRange Constructing Ranges like 0..<0
ExpandoMetaClass A MetaClass that implements GroovyObject and behaves like an Expando, allowing the addition of new methods on the fly.
ExpandoMetaClass.ExpandoMetaConstructor Handles the ability to use the left shift operator to append new constructors
ExpandoMetaClass.ExpandoMetaProperty Instances of this class are returned when using the << left shift operator.

A handle for the MetaClassRegistry that changes all classes loaded into the Grails VM to use ExpandoMetaClass instances

The handle should be registered with the Groovy runtime before Groovy loads, for example in your main method.

GString Represents a String which contains embedded values such as "hello there ${user} how are you?"
GroovyClassLoader for compilation...
GroovyCodeSource CodeSource wrapper class that allows specific security policies to be associated with a class compiled from groovy source.
GroovyLogTestCase Helper class to spoof log entries as produced by calling arbitrary code.
GroovyObjectSupport A useful base class for Java objects wishing to be Groovy objects
GroovyShell Represents a groovy shell capable of running arbitrary groovy scripts
IntRange Represents a list of Integer objects from a specified int up (or down) to and including a given to.
IntRange.IntRangeIterator Iterates through each number in an IntRange.
MetaArrayLengthProperty Represents a property on a bean which may have a getter and/or a setter
MetaBeanProperty Represents a property on a bean which may have a getter and/or a setter
MetaClassImpl Allows methods to be dynamically added to existing classes at runtime
MetaClassRegistry.MetaClassCreationHandle Class used as base for the creation of MetaClass implementations.
MetaClassRegistryChangeEvent An event used to propagate meta class updates
MetaExpandoProperty Represents a property in an Expando object
MetaMethod Represents a Method on a Java object a little like { except without using reflection to invoke the method
MetaProperty Represents a property on a bean which may have a getter and/or a setter
MethodIndexAction given name
NonEmptySequence Represents a sequence of objects which represents one or many instances of of objects of a given type.
ObjectRange Represents an inclusive list of objects from a value to a value using comparators.
ParameterArray Distinguish a parameter array from Object[].
ProxyMetaClass As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs.
Reference Represents a reference to a value
Script This object represents a Groovy script
Sequence Represents a sequence of objects which represents zero or many instances of of objects of a given type.
SpreadMap Represents a spreadable map which extends java.util.HashMap.
Tuple Represents a list of Integer objects from a specified int up to but not including a given and to.

Exception Summary
ClosureException An exception thrown by a closure invocation
DeprecationException Use this exception to mark a method implementation as being deprecated.
GroovyRuntimeException An exception thrown by the interpreter
IllegalPropertyAccessException An exception occurred if a dynamic property dispatch fails with a field not accessible.
IncorrectClosureArgumentsException An exception occurred when invoking a Closure with the wrong number and/or types of arguments
MissingClassException An exception occurred if a dynamic method dispatch fails with an unknown class.
MissingFieldException An exception occurred if a dynamic field dispatch fails with an unknown field.
MissingMethodException An exception occurred if a dynamic method dispatch fails with an unknown method.
MissingPropertyException An exception occurred if a dynamic property dispatch fails with an unknown property.
ReadOnlyPropertyException This exception is thrown if an attempt is made to set a read only property
StringWriterIOException An IO exception occurred trying to append to a StringWriter which should never happen.

Annotation Type Summary
Category Transforms an instance-style Groovy class or interface to become a static-style conventional Groovy category.
Delegate Field annotation to automatically delegate part of the functionality of a class to the annotated field.
Grab Used to grab the referenced artifact and its dependencies and make it available on the Classpath.
Grapes Sometimes we will need more than one grab per class, but we can only add one annotation type per annotatable node.
Immutable Class annotation used for making a class immutable.
Lazy Field annotation to make a field lazy initializable.
Mixin Provides a mechanism for mixing in methods into a class.
Newify Annotation that supports writing constructor call expressions without the 'new' keyword.
PackageScope Class or field annotation used for turning off Groovy's auto property conversion of default or package scoped fields.
Singleton Class annotation to make class singleton.
