Class ProxiedSession

java.lang.Object
  extended by 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

Field Detail

delegate

protected final Session delegate
The proxied instance

Constructor Detail

ProxiedSession

public ProxiedSession(Session target)
Constructs an instance that proxies the specified target. Subclasses may access this target via the protected final 'delegate' attribute, i.e. this.delegate.

Parameters:
target - the specified target Session to proxy.
Method Detail

getId

public Serializable getId()
Immediately delegates to the underlying proxied session.

Specified by:
getId in interface Session
Returns:
The unique identifier assigned to the session upon creation.

getStartTimestamp

public Date getStartTimestamp()
Immediately delegates to the underlying proxied session.

Specified by:
getStartTimestamp in interface Session
Returns:
The time the system created the session.

getLastAccessTime

public Date getLastAccessTime()
Immediately delegates to the underlying proxied session.

Specified by:
getLastAccessTime in interface Session
Returns:
The time the user last interacted with the system.
