Extending the reflection classes
In case you want to create specialized versions of the built-in
classes (say, for creating colorized HTML when being exported,
having easy-access member variables instead of methods or
having utility methods), you may go ahead and extend them.
Example 14-8. Extending the built-in classes <?php
/**
* My ReflectionMethod class
*
*/
class My_ReflectionMethod extends ReflectionMethod {
public $visibility= '';
public function __construct($o, $m) {
parent::__construct($o, $m);
$this->visibility= Reflection::getModifierNames($this->getModifiers());
}
}
/**
* Demo class #1
*
*/
class T {
protected function x() {}
}
/**
* Demo class #2
*
*/
class U extends T {
function x() {}
}
// Print out information
var_dump(new My_ReflectionMethod('U', 'x'));
?> |

Note:
Caution: If you're overwriting the constructor, remember to call
the parent's constructor _before_ any code you insert. Failing to
do so will result in the following:
Fatal error: Internal error: Failed to retrieve the reflection object
