A classe Threaded

(PECL pthreads >= 2.0.0)


Objetos threaded formam a base da capacidade do pthreads de executar código do usuário em paralelo; eles expõem métodos de sincronização e várias interfaces úteis.

Objetos threaded, mais importante ainda, fornecem segurança implícita para o programador; todas as operações no escopo do objeto são seguras.

> Threaded objects, most importantly, provide implicit safety for the programmer; all operations on the object scope are safe.

However, this comes with a trade-off: Operations on the instance scope are slower than on plain PHP objects.

Static properties are not affected as they are thread-local.

It's worth mentioning here that, since v2.0.0, 'Stackable' class was an alias for 'Threaded' class but has been removed since.
