Class Chainer<T>

java.lang.Object
  org.ow2.orchestra.util.Chainer<T>

All Implemented Interfaces:

InvocationHandler

public class Chainer<T>
extends Object
implements InvocationHandler

Generic chainer. This InvocationHandler allows chaining of void only method invocations. If an exception is raised during the invocation of a void method in the chain, then the forwarding is stopped, and the exception will be raised up. Note that if a non-void method is invoked, an IllegalArgumentException is thrown.
