Member Function Documentation

execute()

void execute

(

TaskQueue::Task

task

)

Enqueues a task to be performed on the next idle thread.

getTaskCount()

int getTaskCount

(

)

const

Returns an estimate of the total number of tasks currently in the queue. This estimate is only accurate if the queue has completely stabilized before it is called (i.e. all enqueue and dequeue operations have completed and their memory effects are visible on the calling thread, and no further operations start while this method is being called). Thread-safe.

getThreadCount()

int getThreadCount

(

)

const

Returns the number of threads in the pool.

isStopping()

bool isStopping

(

)

const

Returns whether this thread is shutting down.

resize()

void resize

(

int

numberOfThreads

)

Resizes the number of threads in the pool, joins and exits all existing threads first!

shutDown()

void shutDown

(

)

Sets stopping to true and joins and exits all threads in the pool.
