Detailed Description

Strategize Leader/Follower manipulations in the ORB event loop.

The ORB event loop must participate in the Leader/Followers protocol, but only if that concurrency model is configured, otherwise performance suffers.

This class strategizes the ORB behavior in this respect.

Member Function Documentation

virtual void TAO_LF_Strategy::reset_event_loop_thread (  int    call_reset, TAO_Leader_Follower &    lf )  [pure virtual]

When the thread leaves the event loop a new leader must be elected. Reimplemented in TAO_LF_Strategy_Complete.

virtual int TAO_LF_Strategy::set_event_loop_thread (  ACE_Time_Value *    tv, TAO_Leader_Follower &    lf )  [pure virtual]

Threads that block in the reactor event loop become "server" threads for the Leader/Follower set. They must be flagged specially because they do not wait for one specific event, but for any event whatsoever. Reimplemented in TAO_LF_Strategy_Complete.

virtual void TAO_LF_Strategy::set_upcall_thread (  TAO_Leader_Follower &    lf )  [pure virtual]

Threads that handle requests can block for long periods of time, causing deadlocks if they don't elect a new leader before starting the upcall the system can become non-responsive or dead-lock. Reimplemented in TAO_LF_Strategy_Complete.
