public static final int LOAD_DEFAULT

@Deprecated public static final String MODULE_META_INF_FILE

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

public void addMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)

Adds a listener for constant meta classes.

Parameters:

listener - the listener

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()

public final MetaClass getMetaClass(Class theClass)

public MetaClass getMetaClass(Object obj)

public MetaClassCreationHandle getMetaClassCreationHandler()

Gets a handle internally used to create MetaClass implementations WARNING: experimental code, likely to change soon

Returns:

the handle

public MetaClassRegistryChangeEventListener[] getMetaClassRegistryChangeEventListeners()

Gets an array of all registered ConstantMetaClassListener instances.

public ExtensionModuleRegistry getModuleRegistry()

public FastArray getStaticMethods()

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.

public void registerExtensionModuleFromProperties(Properties properties, ClassLoader classLoader, Map<CachedClass, List<MetaMethod>> map)

public void removeMetaClass(Class theClass)

public void removeMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)

Removes a constant meta class listener.

Parameters:

listener - the listener

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)

public void setMetaClassCreationHandle(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()
