La clase Volatile

(PECL pthreads >= 3.0.0)

Introducción

La clase Volatile es nuevo en pthreads v3. Su introducción es una consecuencia de la nueva semántica de inmutabilidad de Threaded miembros de las clases Threaded. La clase Volatile permite la mutabilidad en arrays PHP en contexto Threaded.

Sinopsis de la Clase

class Volatile extends Threaded implements Collectable, Traversable {

/* Métodos heredados */

public Threaded::chunk(int $size, bool $preserve): array

public Threaded::count(): int

public Threaded::extend(string $class): bool

public Threaded::isRunning(): bool

public Threaded::isTerminated(): bool

public Threaded::merge(mixed $from, bool $overwrite = ?): bool

public Threaded::notify(): bool

public Threaded::notifyOne(): bool

public Threaded::pop(): bool

public Threaded::run(): void

public Threaded::shift(): mixed

public Threaded::synchronized(Closure $block, mixed ...$args): mixed

public Threaded::wait(int $timeout = ?): bool

}

Ejemplos

Ejemplo #1 New immutability semantics of Threaded

<?php

class Task extends Threaded
{
    public function __construct()
    {
        $this->data = new Threaded();

        // intenta sobrescribir una propiedad Threaded de una clase Threaded (inválida)
        $this->data = new StdClass();
    }
}

var_dump((new Task())->data);

El resultado del ejemplo sería algo similar a:

RuntimeException: Threaded members previously set to Threaded objects are immutable, cannot overwrite data in %s:%d

Ejemplo #2 Volatile use-case

<?php

class Task extends Volatile
{
    public function __construct()
    {
        $this->data = new Threaded();

        // intenta sobrescribir una propiedad de Threaded de una clase Volatile (válida)
        $this->data = new StdClass();
    }
}

var_dump((new Task())->data);

El resultado del ejemplo sería algo similar a:

object(stdClass)#3 (0) {
}

<?php

// just use extends  volatile for use array
// is verry good 

class libvar extends Volatile
{
    private $_adresse = '127.0.0.1';
    private $_port = 10000;
    
    public $socket;
    public $list_socket = array();
    public $list_error = array();
    
    public function __construct(){ }
    
    public function set_list($val) { $ct = count($this->list_socket); $this->list_socket[ $ct ] = $val; return $ct; }
    public function set_socket($val) { $this->socket = $val; return $this->socket; }
    public function set_error($val) { $this->list_error[ count($this->list_error) ] = $val; }
    
    public function unset_list($val) { unset($this->list_error[ $val ]); }

    public function get_socketinlist($val) { return $this->list_socket[$val]; }
    public function get_adresse() { return $this->_adresse; }
    public function get_port() { return $this->_port; }
    public function get_socket() { return $this->socket; }
