xdispatch Namespace Reference

Classes
class	operation
	An operation is a functor used to define single portions of work to be dispatched to a single queue. More...
class	iteration_operation
class	ptr_operation
	Provides a template functor to wrap a function pointer to a memberfunction of an object as operation. More...
class	ptr_iteration_operation
	Provides a template functor to wrap a function pointer to a memberfunction of an object as iteration_operation. More...
class	block_operation
	A simple operation for wrapping the given block as an xdispatch::operation. More...
class	object
	The base class of all xdispatch classes. More...
class	group
	A group is a group of operations dispatched on queues. More...
class	queue
	Provides an interface for representing a dispatch queue and methods that can be called to modify or use the queue. More...
class	semaphore
	Wraps dispatch semaphores as provided by libDispatch. More...
struct	any
	Used for transferring data from a sourcetype to source::data without loosing typesafety. More...
class	sourcetype
	Declares an abstract source type. More...
class	source
	Provides a source implementation. More...
class	synclock
	Provides an easy locking mechanism used to ensure the threadsafety of a code area. More...
class	timer
	Provides a timer executing a block or an operation on a specific queue when a timeout occurs. More...
Enumerations

Function Documentation

dispatch_time_t xdispatch::as_delayed_time	(	uint64_t	delay,
		dispatch_time_t	base = DISPATCH_TIME_NOW
	)

Returns:

A dispatch_time_t representing the given delay

Parameters:

delay	The delay in nanoseconds
base	The base to add the delay to, defaults to the current time

dispatch_time_t xdispatch::as_dispatch_time

(

struct tm *

)

Returns:

The given QTime converted to a dispatch_time_t

struct tm xdispatch::as_struct_tm

(

dispatch_time_t

t

)

[read]

Returns:

The given dispatch_time_t as time_t

queue xdispatch::current_queue

(

)

Returns:

The queue the current operation is executed on.

void xdispatch::exec

(

)

Enters the dispatching loop for the main thread.

Call this somewhere within the main thread to enable dispatching operations to the main queue. Will never return.

synclock xdispatch::get_lock_for_key

(

unsigned int

key

)

Returns the synclock used to protect the area identified by the given key.

See also:

synchronized

queue xdispatch::global_queue

(

queue_priority

p = DEFAULT

)

Returns the global queue associated to the given Priority p.

Runnables submitted to these global concurrent queues may be executed concurrently with respect to each other.

Remarks:

Never delete the returned queue!

Returns:

NULL if something went wrong

queue xdispatch::main_queue

(

)

Returns the main queue.

This is the queue running within the main thread. Thus normally only items put on this queue can change the GUI.

Remarks:

Never delete the returned queue!

Returns:

NULL if something went wrong
