TaskQueue

class Firstred\PostNL\Util\TaskQueue: 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.

queue()->run();

public __construct($withShutdown)
public isEmpty()
public add($task)
public run()
public disableShutdown()

Properties

private static property Firstred\PostNL\Util\TaskQueue::$enableShutdown

private static property Firstred\PostNL\Util\TaskQueue::$queue

Methods

public Firstred\PostNL\Util\TaskQueue::__construct($withShutdown=true)

TaskQueue constructor.

Parameters:

$withShutdown (bool)

public Firstred\PostNL\Util\TaskQueue::isEmpty()

Returns:: bool

public Firstred\PostNL\Util\TaskQueue::add($task)

Parameters:

$task (callable)

public Firstred\PostNL\Util\TaskQueue::run()

Returns:: void

public Firstred\PostNL\Util\TaskQueue::disableShutdown(): The task queue will be run and exhausted by default when the process

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.
