## 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]`
