touch

public void touch()
ServiceContext and ServiceGroupContext are not getting automatically garbage collectible. And there is no specific way for some one to go and make it garbage collectable. So the current solution is to make them time out. So the logic is that, there is a timer task in each and every service group which will check for the last touched time. And if it has not been touched for some time, the timer task will remove it from the memory. The touching logic happens like this. Whenever there is a call to addMessageContext in the operationContext it will go and update operationCOntext -> serviceContext -> serviceGroupContext.

Overrides:
touch in class AbstractContext

finalize

protected void finalize()
                 throws Throwable
