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_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_Sched_Priority_Iterator::~ACE_Sched_Priority_Iterator ( void   ) 

Default dtor.


Member Function Documentation

int ACE_Sched_Priority_Iterator::more ( void   )  const

Check if there are more priorities.

void ACE_Sched_Priority_Iterator::next ( void   ) 

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

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

Accessor for the scheduling policy over which we are iterating.

int ACE_Sched_Priority_Iterator::priority ( void   )  const

Return the current priority.

int ACE_Sched_Priority_Iterator::scope ( void   )  const

Accessor for the scheduling.


Member Data Documentation

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.

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

The current priority.
