Class Instance

java.lang.Object

net.e6tech.elements.common.instance.Instance

public class Instance
extends java.lang.Object

This class is used to set fields with Delegate annotation. There are two use cases. First, an instance of the implementation class is created and then delegate fields are set. Second, if the implementation class is an abstract class, an interceptor is created with delegate fields set. In such a case, when a method is called, delegate fields are search to find the most appropriate method to call. In a way, this is somewhat similar to multiple inheritance. Created by futeh.
