Interface DefaultDispatchTarget

All Known Implementing Classes:

BasicObject, Context, Item, User

public interface DefaultDispatchTarget

Interface for an object to handle JSON messages addressed to it for which it does not otherwise have specific methods.

When the MessageDispatcher attempts to deliver a message to an object, it first looks for a JSONMethod attributed method corresponding to the specific message it is trying to deliver. If such a method is found, that method is invoked. However, if there is no such method, then the dispatcher checks whether the object implements this interface; if it does, then it invokes the handleMessage() method to handle it.
