4 | * All operations via the rados gateway are carried out by | |
5 | * small classes known as RGWOps. This class contains a req_state | |
6 | * and each possible command is a subclass of this with a defined | |
7 | * execute() method that does whatever the subclass name implies. | |
8 | * These subclasses must be further subclassed (by interface type) | |
9 | * to provide additional virtual methods such as send_response or get_params. | |
