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

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,
int  restart = 0,
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...


Member Function Documentation

void ACE_Priority_Reactor::dump ( void   )  const [virtual]

Dump the state of an object.

Reimplemented from ACE_Select_Reactor_T< ACE_Select_Reactor_Token >.

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 
) [protected, virtual]

We simply override this function to implement the priority dispatching.

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.

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.

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


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.
