Detailed Description

Define the interface for the Queueing Strategy.

The low-level I/O components in the ORB use this strategy to determine when messages must be queued, immediately sent or flushed.

The strategy isolates this low-level components from the higher level strategies used by the application developer.

Constructor & Destructor Documentation

TAO::Transport_Queueing_Strategy::~Transport_Queueing_Strategy ( void ) [virtual]

Destructor.

virtual bool TAO::Transport_Queueing_Strategy::buffering_constraints_reached	(	TAO_Stub *	stub,
		size_t	msg_count,
		size_t	total_bytes,
		bool &	must_flush,
		const ACE_Time_Value &	current_deadline,
		bool &	set_timer,
		ACE_Time_Value &	interval
	)		const `[pure virtual]`

Return true if it is time to start.

Parameters:

stub	The object used to make the request, this is used to obtain the policies currently in effect for the request
msg_count	The number of messages currently queued
total_bytes	Number of bytes currently queued
set_timer	Returns true if a timer should be set to drain the queue
interval	If set_timer returns 1, this parameter contains the timer interval
must_flush	Is set to true if things must be flushed at this moment

virtual bool TAO::Transport_Queueing_Strategy::must_queue ( bool queue_empty ) const [pure virtual]

Return true if a message must be queued.
