Class ChainGenerator

java.lang.Object
  org.apache.ws.jaxme.js.pattern.ChainGenerator

public class ChainGenerator
extends java.lang.Object

This class generates so-called event chains. A chain is an interface and an object implementing the interface. Internally the implementation is using a list of chained objects, which you can assume to implement the same interface.

Any event is passed to the first object in the list. The object may decide to resolve the event immediately and return. It may also call pass the event to the next object, take the returned value, possibly modify it and return the result. Finally, the chained object may decide to emit another event (which is passed along the same chain), and use the returned value.
