Member Function Documentation

Add()

void CJobPool::Add

(

std::shared_ptr< IJob >

pJob

)

Adds a job to the queue of the job pool.

Parameters

pJob	The job to enqueue.

Remarks

If the job pool is already shutting down, no additional jobs will be enqueue anymore. Abortable jobs will immediately be aborted.

GUARDED_BY() [1/3]

std::shared_ptr< IJob > m_pLastJob CJobPool::GUARDED_BY ( m_Lock )

private

GUARDED_BY() [2/3]

std::shared_ptr< IJob > m_pFirstJob CJobPool::GUARDED_BY ( m_Lock )

private

GUARDED_BY() [3/3]

std::deque< std::shared_ptr< IJob > > m_RunningJobs CJobPool::GUARDED_BY ( m_LockRunning )

private

Init()

void CJobPool::Init

(

int

NumThreads

)

Initializes the job pool with the given number of worker threads.

Parameters

NumThreads

The number of worker threads.

Remarks

Must be called on the main thread.

RunLoop()

void CJobPool::RunLoop ( )

private

Shutdown()

void CJobPool::Shutdown

(

)

Shuts down the job pool. Aborts all abortable jobs. Then waits for all worker threads to complete all remaining queued jobs and terminate.

Remarks

Must be called on the main thread.

WorkerThread()

void CJobPool::WorkerThread ( void * pUser )
