Method Modifiers

警告

These semantics are only applicable to pthreads v2 - they have been removed in pthreads v3.

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 Threaded objects from creation.

例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();
}
?>

例2 private method example: private methods may only be executed by the Threaded object 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();
}
?>
