Class MultiProxy

java.lang.Object

net.e6tech.elements.common.reflection.MultiProxy

public class MultiProxy
extends java.lang.Object

The usage pattern is createProxy().configure() This initial createProxy configures a handler associated with a cls and a list of methods that the handler wishes to intercept. Subsequent configure calls can be made to add more classes and handlers. The main purpose of this class is to intercept certain methods from a class and calls on return values. For example, take EntityManager from JPA, this class can be used to intercept calls on EntityManager and calls on Query. To be more concrete, a call on EntityManager's createQuery produces a Query instance. This class can be configured to intercept calls on such instances. Created by futeh.
