  Description
  ClosureMetaClass
  A metaclass 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 and reflection information and allows methods to be dynamically added to existing classes at runtime
  MetaMethodIndex
  MetaMethodIndex.CacheEntry
  MetaMethodIndex.Entry

  MetaMethodIndex.Header
  MethodMetaProperty
  Wrapper for a method for a property get or set.

  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
