Method Modifiers

pthreads overrides the functionality of the protected and private method modifiers in order to provide functionality more suited to multi-threaded objects. pthreads applies this functionality to all Thread, Worker and Stackable objects from creation.

Example #1 protected method example: protected methods can only be executed by one Thread at a time.


<?php
class ExampleThread extends Thread {
    public function run() {
        /* thread code */
        if ($this->synchronized()) {

        }
    }

    protected function exclusive() {
        /* synchronized method */
    }
}

$thread = new ExampleThread();
if ($thread->start()) {
    $thread->exclusive();
}
?>

Example #2 private method example: private methods may only be executed by the Thread, Worker, or Stackable during execution


<?php
class ExampleThread extends Thread {
    public function run() {
        /* thread code */
        if ($this->insideonly()) {

        }
    }

    private function insideonly() {
        /* private method */
    }
}

$thread = new ExampleThread();
if ($thread->start()) {
    $thread->insideonly();
}
?>
