SelectQueryExtender::extend
public function SelectQueryExtender::extend
public SelectQueryExtender::extend($extender_name)
Enhance this object by wrapping it in an extender object.
Parameters
$extender_name: The base name of the extending class. The base name will be checked against the current database connection to allow driver-specific subclasses as well, using the same logic as the query objects themselves. For example, PagerDefault_mysql is the MySQL-specific override for PagerDefault.
Return value
QueryExtendableInterface The extender object, which now contains a reference to this object.
Overrides QueryExtendableInterface::extend
File
- includes/database/select.inc, line 666
Class
- SelectQueryExtender
- The base extender class for Select queries.
Code
public function extend($extender_name) { // The extender can be anywhere so this needs to go to the registry, which // is surely loaded by now. $class = $this->connection->getDriverClass($extender_name, array(), TRUE); return new $class($this, $this->connection); }
