Method Detail

addMetaClassRegistryChangeEventListener

public void addMetaClassRegistryChangeEventListener(MetaClassRegistryChangeEventListener listener)
Adds a listener for constant meta classes.
Parameters:
listener - the listener

fireConstantMetaClassUpdate

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
