Applies the given QRunnable for async execution in this queue after the given time and returns immediately.
| time | The time to wait until the QRunnable is applied to the queue. |
| virtual void QDispatchQueue::after | ( | QRunnable * | , |

| virtual void xdispatch::queue::after | ( | operation * | , |
| struct tm * | time | ||
| ) | [virtual, inherited] |
Applies the given operation for async execution in this queue after the given time and returns immediately.
The queue will take possession of the operation and handle the deletion. To change this behaviour, set the auto_delete flag of the operation.
| time | The time to wait until the operation is applied to the queue. |

| 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 xdispatch::queue::after | ( | dispatch_block_t | , |
| struct tm * | time | ||
| ) | [virtual, inherited] |
Same as dispatch_after(operation*, time_t).
Will wrap the given block in an operation and put it on the queue.
| virtual void xdispatch::queue::after | ( | dispatch_block_t | , |
| dispatch_time_t | time | ||
| ) | [virtual, inherited] |
| virtual void xdispatch::queue::apply | ( | dispatch_iteration_block_t | , |
| size_t | times | ||
| ) | [virtual, inherited] |
Same as apply(iteration_operation*, size_t times).
Will wrap the given block in an operation and put it on the queue.
| virtual void xdispatch::queue::apply | ( | iteration_operation * | , |
| size_t | times | ||
| ) | [virtual, inherited] |
Applies the given iteration_operation for async execution in this queue and returns immediately.
The operation will be deleted as soon as it was executed the requested number of times. To change this behaviour, set the auto_delete flag of the operation.
| times | The number of times the operation will be executed |
| 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
| 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 xdispatch::queue::async | ( | operation * | ) | [virtual, inherited] |
Will dispatch the given operation for async execution on the queue and return immediately.
The operation will be deleted as soon as it was executed. To change this behaviour, set the auto_delete flag of the operation.
| virtual void xdispatch::queue::async | ( | dispatch_block_t | ) | [virtual, inherited] |
Same as async(operation*).
Will put the given block on the queue.
| virtual void xdispatch::queue::finalizer | ( | operation * | , |
| const queue & | = global_queue() |
||
| ) | [virtual, inherited] |
Sets the given operation as finalizer for this queue.
A finalizer is called before destroying a queue, i.e. if all queue objects representing the queue were deleted and all pending work on a queue was dispatched. The queue will take possession of the operation and handle the deletion. To change this behaviour, set the auto_delete flag of the operation.
When not passing a queue, the finalizer operation will be executed on the queue itself.
| virtual void xdispatch::queue::finalizer | ( | dispatch_block_t | , |
| const queue & | = global_queue() |
||
| ) | [virtual, inherited] |
Same as set_finalizer(operation*, queue*).

| void QDispatchQueue::resume | ( | ) | [virtual, slot] |
Resumes the invocation of work items on this queue.

| 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.
| virtual void QDispatchQueue::setFinalizer | ( | xdispatch::operation * | , |
| const xdispatch::queue & | = xdispatch::global_queue() |
||

| const xdispatch::queue & | = xdispatch::global_queue() |
||
| ) | [virtual] |
| virtual void QDispatchQueue::setTarget | ( | const xdispatch::queue & | ) | [virtual] |
Sets the target queue of this queue, i.e.
the queue all items of this queue will be dispatched on in turn.
| void QDispatchQueue::suspend | ( | ) | [virtual, slot] |
Suspends the invocation of work items on this queue.
A suspended queue will not invoke any blocks associated with it. The suspension of a queue will occur after any running work item associated with the queue completes.
Calls to suspend() must be balanced with calls to resume().
Reimplemented from xdispatch::queue.
| virtual void QDispatchQueue::sync | ( | QRunnable * | ) | [virtual] |
Applies the given QRunnable for execution int his queue and blocks until the QRunnable was executed.
| virtual void xdispatch::queue::sync | ( | dispatch_block_t | ) | [virtual, inherited] |

Will wrap the given block in an operation and put it on the queue.
| virtual void xdispatch::queue::sync | ( | operation * | ) | [virtual, inherited] |
Applies the given operation for execution in this queue and blocks until the operation was executed.
The queue will take possession of the operation and handle the deletion. To change this behaviour, set the auto_delete flag of the operation.
| virtual void xdispatch::queue::target_queue | ( | const queue & | ) | [virtual, inherited] |
Sets the target queue of this queue, i.e.
the queue all items of this queue will be dispatched on in turn.
