Hey guys,
The first design of the PhD Processing Instructions Handler.
The idea is choose the correct PIHandler class for each target you want.
ex:
In the Package_Default_XHTML class we have:
$pihandlers = array(
"dbhtml" => "PI_DBHTMLHandler",
);
In your own package:
$pihandlers = array(
"dbhtml" => "MyOwnDBHTMLHandler",
);
Also we can write a class to handler all targets:
$pihandlers = array(
"dbhtml" => "PIHandler",
"dbman" => "PIHandler",
"tdg-purp" => "PIHandler",
);
The Render class will only know the parsePI method:
case \XMLReader::PI:
$target = $r->name;
$data = $r->value;
foreach ($this as $format) {
$format->parsePI($target, $data);
}
break;
The parsePI method will act like a factory to instanciate the PIHandler
class:
public final function parsePI($target, $data) {
if (isset($this->pihandlers[$target])) {
//I'm thinking in a way to not have to create a new instance
here
//every time. Maybe a singleton?
$classname = __NAMESPACE__ . "\\" . $this->pihandlers[$target];
$pihandler = new $classname($this);
return $pihandler->parse($data);
}
}
The PIHandler classes will have to parse and process the data in the PI.
Sugestions?
