Destructor.
Member Function Documentation
| virtual bool SoBufferAsyncInterface::isInMemory | ( | ) | [pure virtual] |
Return TRUE if the data attached to this buffer are not currently available.
Implemented in SoCpuBufferAsyncBasicProperty.
| virtual void SoBufferAsyncInterface::requestRefetch | ( | SoBufferAsyncNotifierInterface * | asyncNotifier, | |
| const double | weight | |||
| ) | [pure virtual] |
Ask to initiate an ansynchronous load of the data if not already in memory.
Application must call asyncNotifier->refetchNotify() In order to let LDM know that some new data are available.
Implemented in SoCpuBufferAsyncBasicProperty.
