Detailed Description

An iterator over the OS-defined scheduling priorities.

The order of priorities (numeric value vs. importance) is OS dependant, it can be the case that the priorities are not even contigous. This class permits iteration over priorities using the iterator pattern.


Constructor & Destructor Documentation

ACE_INLINE ACE_Sched_Priority_Iterator::ACE_Sched_Priority_Iterator const ACE_Sched_Params::Policy policy,
int  scope = ACE_SCOPE_THREAD
 

Initialize the iterator, the arguments define the scheduling policy and scope for the priorities (see ACE_Sched_Param).

ACE_INLINE ACE_Sched_Priority_Iterator::~ACE_Sched_Priority_Iterator void   ) 
 

Default dtor.


Member Function Documentation

ACE_INLINE int ACE_Sched_Priority_Iterator::more void   )  const
 

Check if there are more priorities.

ACE_INLINE void ACE_Sched_Priority_Iterator::next void   ) 
 

Move to the next priority. The iteration is from lowest to highest importance.

ACE_INLINE const ACE_Sched_Params::Policy & ACE_Sched_Priority_Iterator::policy void   )  const
 

Accessor for the scheduling policy over which we are iterating.

ACE_INLINE int ACE_Sched_Priority_Iterator::priority void   )  const
 

Return the current priority.

ACE_INLINE int ACE_Sched_Priority_Iterator::scope void   )  const
 

Accessor for the scheduling.


Member Data Documentation

int ACE_Sched_Priority_Iterator::done_ [private]
 

This is set to 1 when there are no more priorities. Cannot easily compare against the highest priority on platforms were priorities are non-contigous or descending.

ACE_Sched_Params::Policy ACE_Sched_Priority_Iterator::policy_ [private]
 

The Scheduling policy (FIFO, RR, etc.) and scheduling scope (PROCESS, SYSTEM) we are iterating on.

int ACE_Sched_Priority_Iterator::priority_ [private]
 

The current priority.

int ACE_Sched_Priority_Iterator::scope_ [private]
