Detailed Description

Implements priority based dispatching.

This class refines the dispatching mechanism for the Select_Reactor by taking advantage of the priority method on ACE_Event_Handler.

There is a queue per-priority, which simply holds the Event_Handlers until we know who goes first.

ACE_Priority_Reactor::ACE_Priority_Reactor	(	ACE_Sig_Handler *	sh = `0`,
		ACE_Timer_Queue *	tq = `0`
	)

Initialize ACE_Priority_Reactor with the default size.

ACE_Priority_Reactor::ACE_Priority_Reactor	(	size_t	size,
		bool	restart = `false`,
		ACE_Sig_Handler *	sh = `0`,
		ACE_Timer_Queue *	tq = `0`
	)

Initialize ACE_Priority_Reactor with size size.

ACE_Priority_Reactor::~ACE_Priority_Reactor ( void ) [virtual]

Close down the select_reactor and release all of its resources.

ACE_Priority_Reactor::ACE_Priority_Reactor ( const ACE_Priority_Reactor & ) [private]

Deny access since member-wise won't work...

int ACE_Priority_Reactor::build_bucket	(	ACE_Handle_Set &	dispatch_mask,
		int &	min_priority,
		int &	max_priority
	)			`[private]`

Build the bucket from the given dispatch_mask. Return -1 on failure, 0 otherwise.

		int &	number_dispatched,
		int	mask,
		ACE_Handle_Set &	dispatch_mask,
		ACE_Handle_Set &	ready_mask,
		ACE_EH_PTMF	callback
