Detailed Description

Define the interface for the connect strategy, i.e. the algorithm that controls how does the ORB establishes remote connections.

The thread that establishes remote connections can either make a blocking or a non-blocking connect. The strategy to wait for the connection completion can also be different.

This strategy controls how does the ORB schedules and waits for connection completion.

Constructor & Destructor Documentation

TAO_Connect_Strategy::TAO_Connect_Strategy

(

TAO_ORB_Core *

orb

)

Constructor.

TAO_Connect_Strategy::~TAO_Connect_Strategy ( void  )

virtual

Destructor.

Member Function Documentation

int TAO_Connect_Strategy::poll

(

TAO_LF_Multi_Event *

ev

)

Do a quick check to see if any connections are complete. This does the same as the wait with an explicit time value of 0.

virtual void TAO_Connect_Strategy::synch_options ( ACE_Time_Value *  val, ACE_Synch_Options &  opt  )

pure virtual

Obtain the synch options that can be passed to ACE_Connector.

Return the synch option for the connector, based on the timeout and the strategy in place. ACE_Connectors behavior can be altered by passing the right ACE_Synch_Options to the connect () call.

Implemented in TAO_LF_Connect_Strategy, TAO_Reactive_Connect_Strategy, and TAO_Blocked_Connect_Strategy.

int TAO_Connect_Strategy::wait	(	TAO_Connection_Handler *	ch,
		ACE_Time_Value *	val
	)

Wait for the connection to be completed till a timeout occurs.

If the connection establishment fails the state within the connection handler is set appropriately.

int TAO_Connect_Strategy::wait	(	TAO_Transport *	t,
		ACE_Time_Value *	val
	)

int TAO_Connect_Strategy::wait	(	TAO_LF_Multi_Event *	ev,
		ACE_Time_Value *	val
	)

Wait for one of many connections to complete. Returns when one succeeds or all fail.

virtual int TAO_Connect_Strategy::wait_i ( TAO_LF_Event *  ev, TAO_Transport *  t, ACE_Time_Value *  val  )

protectedpure virtual

This is the method that does all the real interesting stuff.

Implemented in TAO_LF_Connect_Strategy, TAO_Reactive_Connect_Strategy, and TAO_Blocked_Connect_Strategy.
