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!
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
MixedInMetaClass |
MixinInstanceMetaMethod | MetaMethod for mixed in classes
MixinInstanceMetaProperty | MetaProperty for mixed in classes
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
Exception | Description

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.
