public function QueryExtendableInterface::extend
public QueryExtendableInterface::extend($extender_name)
Enhance this object by wrapping it in an extender object.
Parameters
$extender_name: The base name of the extending class. The base name will be checked against the current database connection to allow driver-specific subclasses as well, using the same logic as the query objects themselves. For example, PagerDefault_mysql is the MySQL-specific override for PagerDefault.
Return value
QueryExtendableInterface The extender object, which now contains a reference to this object.
