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.
GeneratedGroovyProxy	An interface implemented by some Groovy proxies which gives access to the proxied object.
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 discrete items between some starting (or from) value and working up towards some ending (or 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.

Annotation Types Summary

Annotation Type	Description
Category	Transforms an instance-style Groovy class or interface to become a static-style conventional Groovy category.
Delegate	Annotation to automatically delegate part of the functionality of an owner class to the annotated delegation target.
DelegatesTo	This annotation can be used by API or DSL writers to document parameters which accept a closure.
DelegatesTo.Target	Parameter annotation used to specify the delegate for a @DelegatesTo annotated parameter of the same method.
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 (a transitive dependency) 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.
Groovydoc	An annotation to hold the groovydoc for the annotated element at runtime, we call it "Runtime Groovydoc".
Lazy	Field annotation to simplify lazy initialization.
Mixin	Deprecated. static mixins have been deprecated in favour of traits (trait keyword).
Newify	Annotation that supports writing constructor call expressions without the 'new' keyword.
Singleton	Class annotation to make a singleton class.
