Usage

To use the ObjectStorage class, you must extend it with your own class.

use Herrera\Util\ObjectStorage;

/**
 * This is your class.
 */
class MyObjectStorage extends ObjectStorage
{
    /**
     * @override
     */
    public function isSupported($object)
    {
        return ($object instanceof DateTime);
    }
}

In the example above, MyObjectStorage class will only permit DateTime to be added. Any attempt to add a different type of object will result in an exception (UnexpectedValueException) being thrown with the following message: The object, SomeClass, is not supported.

How you implement the isSupported() method is entirely up to you. The method only needs to return true if the object it is given is supported, or false if it is not.
