Clone magic method.

Select queries have dependent objects that must be deep-cloned. The connection object itself, however, should not be cloned as that would duplicate the connection itself.

Class

SelectQueryExtender

The base extender class for Select queries.

Code

public function __clone() {
 $this->uniqueIdentifier  = uniqid ('', TRUE);
 // We need to deep-clone the query we're wrapping, which in turn may
 // deep-clone other objects. Exciting!
 $this->query  = clone $this->query ;
}
