- Class Summary
  Class | Description
  --- | ---
  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 and 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 |
