aggregate_info

(no version information, might be only in CVS)

aggregate_info —
Returns an associative array of the methods and properties from
each class that has been aggregated to the object
Descriptionarray aggregate_info ( object object )

Will return the aggregation information for a particular object
as an associative array of arrays of methods and properties. The
key for the main array is the name of the aggregated class.

For example the code below

Example 1. Using aggregate_info()

 
class Slicer {
    var $vegetable;
 
    function Slicer($vegetable) 
    {
        $this->vegetable = $vegetable;
    }
 
    function slice_it($num_cuts) 
    {
        echo "Doing some simple slicing\n";
        for ($i=0; $i < $num_cuts; $i++) {
            // do some slicing
        }
    }
}
 
class Dicer {
    var $vegetable;
    var $rotation_angle = 90;   // degrees
 
    function Dicer($vegetable) 
    {
        $this->vegetable = $vegetable;
    }
 
    function dice_it($num_cuts) 
    {
        echo "Cutting in one direction\n";
        for ($i=0; $i < $num_cuts; $i++) {
            // do some cutting
        }
        $this->rotate($this->rotation_angle);
        echo "Cutting in a second direction\n";
        for ($i=0; $i < $num_cuts; $i++) {
            // do some more cutting
        }
    }
 
    function rotate($deg) 
    {
        echo "Now rotating {$this->vegetable} {$deg} degrees\n";
    }
 
    function _secret_super_dicing($num_cuts) 
    {
        // so secret we cannot show you ;-)
    }
}
 
$obj = new Slicer('onion');
aggregate($obj, 'Dicer');
print_r(aggregate_info($obj));

Will produce the output

Array
(
[dicer] => Array
(
[methods] => Array
(
[0] => dice_it
[1] => rotate
)

[properties] => Array
(
[0] => rotation_angle
)

)

)
As you can see, all properties and methods of the
Dicer class have been aggregated
into our new object, with the exception of the class
constructor and the method _secret_super_dicing
