Resolve php "deadlock"
- by Matt
Hey all,
I'm currently running into a situation that I guess would be called deadlock.
I'm implementing a message service that calls various object methods.. it's quite similar to observer pattern..
Here's whats going on:
Dispatcher.php
Dispatcher.php
<?
class Dispatcher {
...
public function message($name, $method) {
// Find the object based on the name
$object = $this->findObjectByName($name);
// Slight psuedocode.. for ease of example
if($this->not_initialized($object))
$object = new $object(); // This is where it locks up.
}
return $object->$method();
...
}
class A {
function __construct()
{
$Dispatcher->message("B", "getName");
}
public function getName() {
return "Class A";
}
}
class B {
function __construct()
{
// Assume $Dispatcher is the classes
$Dispatcher->message("A", "getName");
}
public function getName() {
return "Class B";
}
}
?>
It locks up when neither object is initialized. It just goes back and forth from message each other and no one can be initialized.
Any help would be immensely helpful..
Thanks!
