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.

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
	)		[protected, pure 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.
