Constructor & Destructor Documentation

virtual SoBufferAsyncInterface::~SoBufferAsyncInterface (  )  [inline, virtual]

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.
