| Methods' Summary | |
| isValid | Query whether this volatile bitmap still has valid content. As the video RAM allocated to this bitmap can be reclaimed at any time, a return value of true here does not imply that the next draw operation with this bitmap will succeed. Instead, the exception VolatileContentDestroyed will be thrown then. |
