Detailed Description

Use the Leader/Follower loop to wait for one specific event in the invocation path.

Used by the parallel connection strategy for waiting on one of many connections.

Member Function Documentation

void TAO_LF_Multi_Event::add_event ( TAO_Connection_Handler * ch )

Adds a handler to the collection.

TAO_Transport * TAO_LF_Multi_Event::base_transport ( void )

Returns the transport associated with the first entry in the collection.

int TAO_LF_Multi_Event::bind ( TAO_LF_Follower * follower ) [virtual]

propogate the follower to all the events in the collection.

Reimplemented from TAO_LF_Event.

int TAO_LF_Multi_Event::error_detected ( void ) const [virtual]

Return 1 if an error was detected while waiting for the event - This iterates over the list of events and returns 1 only if all of them return 1 from error_detected.

Implements TAO_LF_Event.

int TAO_LF_Multi_Event::is_state_final ( void ) [protected, virtual]

Check whether we have reached the final state..

Implements TAO_LF_Event.

void TAO_LF_Multi_Event::operator= ( const TAO_LF_Multi_Event & ) [private]

void TAO_LF_Multi_Event::state_changed_i ( int new_state ) [protected, virtual]

Validate the state change.

Implements TAO_LF_Event.

int TAO_LF_Multi_Event::successful ( void ) const [virtual]

Return 1 if the condition was satisfied successfully, 0 if it has not - This iterates over the list of attached events and returns 1 if any of them return 1 from successful.

Implements TAO_LF_Event.

int TAO_LF_Multi_Event::unbind ( TAO_LF_Follower * follower ) [virtual]

Unbind the follower from all the collected events.

Reimplemented from TAO_LF_Event.

TAO_Connection_Handler * TAO_LF_Multi_Event::winner ( void )

Returns the connection handler that caused the successful status to be returned.
