Class ProxiedSession

java.lang.Object
  org.apache.shiro.session.ProxiedSession

All Implemented Interfaces:

Session

Direct Known Subclasses:

ImmutableProxiedSession

public class ProxiedSession
extends Object
implements Session

Simple Session implementation that immediately delegates all corresponding calls to an underlying proxied session instance.

This class is mostly useful for framework subclassing to intercept certain Session calls and perform additional logic.

Since:

0.9
