Pool::__construct

(PECL pthreads >= 2.0.0)

Pool::__constructCreates a new Pool of Workers

説明

public Pool::__construct(int $size, string $class = ?, array $ctor = ?)

Construct a new pool of workers. Pools lazily create their threads, which means new threads will only be spawned when they are required to execute tasks.

パラメータ

size

The maximum number of workers for this pool to create

class

The class for new Workers. If no class is given, then it defaults to the Worker class.

ctor

An array of arguments to be passed to new workers' constructors

例1 Creating Pools

<?php
class MyWorker extends Worker {

public function
__construct(Something $something) {
$this->something = $something;
}

public function
run() {
/** ... **/
}
}

$pool = new Pool(8, \MyWorker::class, [new Something()]);

var_dump($pool);
?>

上の例の出力は以下となります。

object(Pool)#1 (6) {
  ["size":protected]=>
  int(8)
  ["class":protected]=>
  string(8) "MyWorker"
  ["workers":protected]=>
  NULL
  ["work":protected]=>
  NULL
  ["ctor":protected]=>
  array(1) {
    [0]=>
    object(Something)#2 (0) {
    }
  }
  ["last":protected]=>
  int(0)
}
