Method Detail

adhere

void adhere()

Adhere to the session, so the instance of this action will persist until disjoin is called.

disjoin

void disjoin()

Remove this action from session and discard its instance losing all state (instance variables) associated with it.

onRemoved

void onRemoved()

This method will be called if the session has expired or if it has been invalidated and there are sticky actions still sticked to the session. This is very useful for clean up and will be called if your action calls adhere and forget to call disjoin, leaving the actiion instance forever in the session.
