public function SelectExtender::addMetaData

public SelectExtender::addMetaData($key, $object)

Parameters

$key: The unique identifier for this piece of metadata. Must be a string that follows the same rules as any other PHP identifier.

$object: The additional data to add to the query. May be any valid PHP variable.

Return value
