Pool::__construct — Creates a new Pool of Workers
Description
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.
Parameters
-
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
Examples
Example #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);
?>
The above example will output:
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)
}
