TaskQueue{} Yoast 1.0

A task queue that executes tasks in a FIFO order.

This task queue class is used to settle promises asynchronously and maintains a constant stack size. You can use the task queue asynchronously by calling the run() function of the global task queue in an event loop.


Хуков нет.


Null. Ничего.


$TaskQueue = new TaskQueue();
// use class methods


  1. __construct($withShutdown = \true)
  2. add(callable $task)
  3. disableShutdown()
  4. isEmpty()
  5. run()

     * exits IFF the exit is not the result of a PHP E_ERROR error.
     * You can disable running the automatic shutdown of the queue by calling
     * this function. If you disable the task queue shutdown process, then you
     * MUST either run the task queue (as a result of running your event loop
     * or manually using the run() method) or wait on each outstanding promise.
     * Note: This shutdown will occur before any destructors are triggered.
