com.thoughtworks.proxy.kit.ObjectReference
A way to refer to objects that are stored in "awkward" places (for example inside a HttpSession or {@link ThreadLocal}). This interface is typically implemented by someone integrating with an existing container. @author Joe Walnes @since 0.2, 0.1 in package com.thoughtworks.proxy.toy.delegate
