PvRawData::GetPayloadLength
virtual uint64_t GetPayloadLength() const =0
Get the payload length specified in the leader information of this block.
PvRawData::Free
virtual void Free()=0
Frees (de-allocates) the buffer's internal memory.
PvRawData::Attach
virtual PvResult Attach(void *aRawBuffer, uint64_t aPayloadLength, uint32_t aMaximumChunkLength=0)=0
