I have a "parent" component that I want to use to implement an
"interface" (java style) and multple "child" components that extend
the "interface". I want my controllers to instantiate a specific
"child" component, but in the code I want to reference all methods
through the "parent" class or "inteface"
class ParentComponent extends Object {}
class TypeAComponent extends InterfaceComponent {
function someMethod() { return "a";}
}
class TypeBComponent extends InterfaceComponent {
function someMethod() { return 'b';}
}
class MyController extends AppController {
var $components('TypeAComponent');
function example() {
$result = $this->Parent->someMethod();
}
}
The example above works fine. But I cannot figure out how to load
'TypeAComponent' or 'TypeBComponent' dynamically. How can I set
MyConfroller->components BEFORE the controller loads the components?
Or how do I load additional components afterwards?
I tried this in ParentComponent, but while the subclassed components
constructors were called properly, the components were not "loaded"
the same way (i.e. the child component's var $component array were not
loaded, i.e. Session.)
class ParentComponent extends Object {
static function create($type) {
switch ($type) {
case 'TypeA':
include_once(dirname(__FILE__).DS.'typeA.php');
return new TypeAComponent();
break;
case 'TypeB':
include_once(dirname(__FILE__).DS.'typeB.php');
return new TypeBComponent();
break;
}
}
}
