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.


Member Typedef Documentation

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


Constructor & Destructor Documentation

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.

Close down the select_reactor and release all of its resources.

Member Function Documentation

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 ACE_Priority_Reactor::dispatch_io_set ( int  number_of_active_handles,
int &  number_dispatched,
int  mask,
ACE_Handle_Set dispatch_mask,
ACE_Handle_Set ready_mask,
ACE_EH_PTMF  callback 
)
protectedvirtual

We simply override this function to implement the priority dispatching.

Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

void ACE_Priority_Reactor::dump ( void  ) const
virtual

Dump the state of an object.

Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

void ACE_Priority_Reactor::init_bucket ( void  )
private

A small helper to initialize the bucket.

Member Data Documentation

Declare the dynamic allocation hooks.

Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

The queues themselves use this allocator to minimize dynamic memory usage.
