listener
- the listenerAdds a listener for constant meta classes. This listener cannot be removed!
listener
- the listenerCauses 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.
obj
- object instance if the MetaClass change is on a per-instance metaclass (or null if global)c
- the classoldMC
- the old MetaClassnewMc
- the new MetaClassSingleton of MetaClassRegistry.
Gets a handle internally used to create MetaClass implementations WARNING: experimental code, likely to change soon
Gets an array of of all registered ConstantMetaClassListener instances.
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.
Removes a constant meta class listener.
listener
- the listenerRegisters a new MetaClass in the registry to customize the type
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
