    Pool::submitTo — Submits a task to a specific worker for execution

    説明

    public Pool::submitTo(int $worker, Threaded $task): int

    Submit a task to the specified worker in the pool. The workers are indexed from 0, and will only exist if the pool has needed to create them (since threads are lazily spawned).

    パラメータ

    worker

    The worker to stack the task onto, indexed from 0.

    task

    The task for execution.

    戻り値

    The identifier of the worker that accepted the task.

    例

    例1 Submitting tasks to a specific worker

    <?php
    class Task extends Threaded {
    public function     run() {
    var_dump(Thread::getCurrentThreadID());
    }
    }

    $pool = new Pool(2);

    $pool->submit(new Task());

    for (    $i = 0; $i < 5; ++$i) {
    $pool->submitTo(0, new Task()); // stack all tasks onto the first worker
    }

    $pool->submitTo(1, new Task()); // cannot stack the task onto the second worker due to it not existing yet

    $pool->shutdown();

    上の例の出力は以下となります。

    int(4475011072)
int(4475011072)
int(4475011072)
int(4475011072)
int(4475011072)
int(4475011072)
