Interface SourceRetargeter

public interface SourceRetargeter

Interface for an object that can be a source of JSON messages on behalf of other objects. This provides a linkage between the object that actually pulls the message off of a network connection and the object that the message is represented to its receiver as being from. In other words, this interface gives the object that does the actual work of receiving a message the opportunity to substitute some object other than itself as the 'from' parameter to the message handler.

Compare and contrast with MessageRetargeter.
