groovy.lang (Groovy 2.1.8)

Interface Summary
Interface	Description
AdaptingMetaClass	An interface for MetaClass instances that "adapt" other MetaClass instances such as a proxy or delegating MetaClass.
Buildable
ClosureInvokingMethod	An interface for MetaMethods that invoke closures to implements.
GroovyCallable<V>	A special "marker" style interface allowing Groovy classes to implement both Runnable and Callable yet give preference to Runnable (for backwards compatibility) for APIs having both Runnable and Callable methods.
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.
MetaObjectProtocol	An interface that defines the API usable by clients of Groovy's Meta Object Protocol (MOP).
MutableMetaClass	An interface that defines methods that implementers of mutable Meta classes should specify.
PropertyAccessInterceptor	An interface that adds the ability to intercept property getters/setters
Range<T extends Comparable>	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
Class	Description
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<V>	Represents any closure object in Groovy.
DelegatingMetaClass
EmptyRange	Constructing Ranges like 0..<0
ExpandoMetaClass	ExpandoMetaClass is a MetaClass that behaves like an Expando, allowing the addition or replacement of methods, properties and constructors on the fly.
ExpandoMetaClassCreationHandle	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.
GroovyClassLoader	A ClassLoader which can load Groovy classes.
GroovyClassLoader.ClassCollector
GroovyClassLoader.InnerLoader
GroovyCodeSource	CodeSource wrapper class that allows specific security policies to be associated with a class compiled from groovy source.
GroovyObjectSupport	A useful base class for Java objects wishing to be Groovy objects
GroovyShell	Represents a groovy shell capable of running arbitrary groovy scripts
GroovySystem
GString	Represents a String which contains embedded values such as "hello there ${user} how are you?"
IntRange	Represents a list of Integer objects from a specified int up (or down) to and including a given to.
ListWithDefault<T>	A wrapper for `List` which automatically grows the list when either `ListWithDefault.get(int)` or `ListWithDefault.getAt(int)` is called with an index greater than or equal to `size()`.
MapWithDefault<K,V>	A wrapper for Map which allows a default value to be specified.
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
MetaClassImpl.Index
MetaClassImpl.MetaConstructor	This is a helper class introduced in Groovy 2.1.0, which is used only by indy.
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 `Method` except without using reflection to invoke the method
MetaProperty	Represents a property on a bean which may have a getter and/or a setter
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[].
PropertyValue
ProxyMetaClass	As subclass of MetaClass, ProxyMetaClass manages calls from Groovy Objects to POJOs.
Reference<T>	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.
TracingInterceptor
Tuple	Represents a list of Integer objects from a specified int up to but not including a given and to.

Exception Summary
Exception	Description
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
SpreadListEvaluatingException
SpreadMapEvaluatingException
StringWriterIOException	An IO exception occurred trying to append to a StringWriter which should never happen.

Annotation Types Summary
Annotation Type	Description
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 an owner class to the annotated field.
DelegatesTo	This annotation can be used by API or DSL writers to document parameters which accept a closure.
DelegatesTo.Target
Grab	Used to grab the referenced artifact and its dependencies and make it available on the Classpath.
GrabConfig	Used to modify the grape configuration for grab requests.
GrabExclude	Used to exclude an indirectly referenced artifact from the classpath.
GrabResolver	Used to add a repository for resolving Grape dependencies.
Grapes	Sometimes we will need more than one grab per class, but we can only add one annotation type per annotatable node.
Lazy	Field annotation to simplify lazy initialization.
Mixin	Provides a mechanism for mixing in methods into a class.
Newify	Annotation that supports writing constructor call expressions without the 'new' keyword.
Singleton	Class annotation to make class singleton.

Package groovy.lang Description

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