| 12 * This interface does not strictly define what happens when the priority of an | |
| 13 * object is changed. An implementation of this interface is free to define | |
| 14 * the side-effects of changing the priority of an object. In some cases, | |
| 15 * changing the priority of an object may be disallowed (resulting in an | |
| 16 * exception being thrown) or may simply be ignored. | |
