Pool::__construct — Creates a new Pool of Workers

説明

public Pool::__construct ( int $size [, string $class [, array $ctor ]] ) : Pool

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

返り値

例

例1 Creating Pools

<?phpclass 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)
}
