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

Propagate 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  )

protectedvirtual

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 )

protectedvirtual

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.
