Class Summary
ClosureMetaClass: A meta class for closures generated by the Groovy compiler.
ClosureMetaMethod: A MetaMethod that accepts a closure in the constructor which is invoked when the MetaMethod is called.
ClosureStaticMetaMethod: This class represents a MetaMethod that is a closure that pretends to be a static method.
ConcurrentReaderHashMap: A hash table that supports mostly-concurrent reading, but exclusive writing.
ConcurrentReaderHashMap.BarrierLock: A Serializable class for barrier lock
ConcurrentReaderHashMap.Entry: ConcurrentReaderHashMap collision list entry.
DefaultMetaClassInfo: WARNING: This class is for internal use only! We use this class to store information about if a default MetaClass is used for certain primitives.
DefaultMetaClassInfo.ConstantMetaClassVersioning
MetaClassRegistryImpl: A registry of MetaClass instances which caches introspection & reflection information and allows methods to be dynamically added to existing classes at runtime
MetaMethodIndex
MetaMethodIndex.CacheEntry
MetaMethodIndex.Entry
MetaMethodIndex.Header
MethodHelper: Some reflection helper methods
MethodMetaProperty: Wrapper for a method for a property get or set.
MethodMetaProperty.GetBeanMethodMetaProperty: Wrapper for a method realizing the property getter.
MethodMetaProperty.GetMethodMetaProperty: Wrapper for a method realizing the property get.
MixedInMetaClass
MixinInstanceMetaMethod: MetaMethod for mixed in classes
MixinInstanceMetaProperty: MetaProperty for mixed in classes
MultipleSetterProperty: This class represents a property with multiple setters.
NewInstanceMetaMethod: A MetaMethod implementation where the underlying method is really a static helper method on some class but it appears to be an instance method on a class.
NewMetaMethod: Base class for NewInstanceMetaMethod and NewStaticMetaMethod
NewStaticMetaMethod: A MetaMethod implementation where the underlying method is really a static helper method on some class.
OwnedMetaClass
ReflectionMetaMethod
ReflectorLoader: Reflector creation helper.
TemporaryMethodKey: A temporary implementation of MethodKey used to perform a fast lookup for a method using a set of arguments to a method
ThreadManagedMetaBeanProperty: This MetaBeanProperty will create a pseudo property whose value is bound to an object using weak references.
TransformMetaMethod: A MetaMethod implementation useful for implementing coercion based invocations

Exception Summary
MethodSelectionException: This exception is thrown if the runtime is unable to select a method.
MissingMethodExceptionNoStack
MissingMethodExecutionFailed: A stack less exception used to indicate, that the execution of a missingMethod method failed with a MissingMethodException.
MissingPropertyExceptionNoStack
