Member Function Documentation

virtual void QDispatchQueue::after	(	QRunnable *	,
		const QTime &	time
	)		[virtual]

Applies the given QRunnable for async execution in this queue after the given time and returns immediately.

Parameters:

time	The time to wait until the QRunnable is applied to the queue.

virtual void QDispatchQueue::after	(	QRunnable *	,
		dispatch_time_t	time
	)		[virtual]

virtual void QDispatchQueue::after	(	dispatch_block_t	,
		const QTime &	time
	)		[virtual]

Same as after().

Will wrap the given block in a QRunnable and put it on the queue.

virtual void QDispatchQueue::apply	(	QIterationRunnable *	,
		int	times
	)		[virtual]

Applies the given QRunnable for async execution in this queue and returns immediately.

In case the autoDelete() flag of the passed QIterationRunnable is set to true it is ensured that the runnable will be deleted after being executed the requested number of times

Parameters:

times

The number of times the QRunnable will be executed

virtual void QDispatchQueue::async

(

QRunnable *

)

[virtual]

Applies the given QRunnable for async execution in this queue and returns immediately.

virtual void QDispatchQueue::set_finalizer	(	QRunnable *	,
		const xdispatch::queue &	= xdispatch::global_queue()
	)		[virtual]

Sets the given runnable as finalizer for this queue.

A finalizer is called before destroying a queue, i.e. if all QDispatchQueue objects representing the queue were deleted and all pending work on a queue was dispatched.

Remarks:

Finalizers will never be called on the global queues or the main queue.

virtual void QDispatchQueue::sync

(

QRunnable *

)

[virtual]

Applies the given QRunnable for execution int his queue and blocks until the QRunnable was executed.
