Member Function Documentation

◆ isInMemory()

virtual bool SoBufferAsyncInterface::isInMemory ( )
pure virtual

Return TRUE if the data attached to this buffer are not currently available.

Implemented in SoCpuBufferAsyncBasicProperty.

◆ requestRefetch()

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.
