org.codehaus.groovy.runtime.metaclass.MetaClassRegistryImpl

All Implemented Interfaces and Traits:

MetaClassRegistry
```
public class MetaClassRegistryImpl
extends Object
implements MetaClassRegistry
```
A registry of MetaClass instances which caches introspection and reflection information and allows methods to be dynamically added to existing classes at runtime

  - public static final int LOAD_DEFAULT
  - @Deprecated
    public static final String MODULE_META_INF_FILE
    
    deprecated:
    Use ExtensionModuleScanner.MODULE_META_INF_FILE instead
- Constructor Detail
  - public MetaClassRegistryImpl()
  - public MetaClassRegistryImpl(int loadDefault)
  - public MetaClassRegistryImpl(boolean useAccessible)
    
    Parameters:
    useAccessible - defines whether or not the AccessibleObject.setAccessible method will be called to enable access to all methods when using reflection
  - public MetaClassRegistryImpl(int loadDefault, boolean useAccessible)
- Method Detail
  - @Override
    public void addMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)
    
    Adds a listener for constant meta classes.
    Parameters:
    listener - the listener
  - @Override
    public void addNonRemovableMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)
    
    Adds a listener for constant meta classes. This listener cannot be removed!
    Parameters:
    listener - the listener
  - protected void fireConstantMetaClassUpdate(Object obj, Class c, MetaClass oldMC, MetaClass newMc)
    
    Causes the execution of all registered listeners. This method is used mostly internal to kick of the listener notification. It can also be used by subclasses to achieve the same.
    Parameters:
    obj - object instance if the MetaClass change is on a per-instance metaclass (or null if global)
    c - the class
    oldMC - the old MetaClass
    newMc - the new MetaClass
  - public static MetaClassRegistry getInstance(int includeExtension)
    
    Singleton of MetaClassRegistry.
    Parameters:
    includeExtension
    Returns:
    the registry
  - public FastArray getInstanceMethods()
  - @Override
    public final MetaClass getMetaClass(Class theClass)
  - public MetaClass getMetaClass(Object obj)
  - @Override
    public MetaClassRegistry.MetaClassCreationHandle getMetaClassCreationHandler()
    
    Gets a handle internally used to create MetaClass implementations WARNING: experimental code, likely to change soon
    Returns:
    the handle
  - @Override
    public MetaClassRegistryChangeEventListener[] getMetaClassRegistryChangeEventListeners()
    
    Gets an array of all registered ConstantMetaClassListener instances.
  - public ExtensionModuleRegistry getModuleRegistry()
  - public FastArray getStaticMethods()
  - @Override
    public boolean hasNext()
  - @Override
    public Iterator iterator()
    
    Returns an iterator to iterate over all constant meta classes. This iterator can be seen as making a snapshot of the current state of the registry. The snapshot will include all meta classes that has been used unless they are already collected. Collected meta classes will be skipped automatically, so you can expect that each element of the iteration is not null. Calling this method is thread safe, the usage of the iterator is not.
    Returns:
    the iterator.
  - @Override
    public Object next()
  - public void registerExtensionModuleFromProperties(Properties properties, ClassLoader classLoader, Map<CachedClass, List<MetaMethod>> map)
  - @Override
    public void remove()
  - @Override
    public void removeMetaClass(Class theClass)
  - @Override
    public void removeMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)
    
    Removes a constant meta class listener.
    Parameters:
    listener - the listener
  - @Override
    public void setMetaClass(Class theClass, MetaClass theMetaClass)
    
    Registers a new MetaClass in the registry to customize the type
    Parameters:
    theClass
    theMetaClass
  - public void setMetaClass(Object obj, MetaClass theMetaClass)
  - @Override
    public void setMetaClassCreationHandle(MetaClassRegistry.MetaClassCreationHandle handle)
    
    Sets a handle internally used to create MetaClass implementations. When replacing the handle with a custom version, you should reuse the old handle to keep custom logic and to use the default logic as fall back. WARNING: experimental code, likely to change soon
    Parameters:
    handle - the handle
  - public boolean useAccessible()
