Detailed Description

A std::istream-like input data stream for binary data.

Derived classes send the data using command packets.

Definition at line 23 of file dataIStream.h.

Basic data input
template<typename T>
DataIStream &	operator>> (T &value)
	Read a POD data item.
template<typename T>
DataIStream &	operator>> (std::vector< T > &value)
	Read a std::vector of POD data items.
void	read (void *data, uint64_t size)
	Read a number of bytes into a buffer.
const void *	getRemainingBuffer ()
	Get the pointer to the data remaining in the current buffer.
uint64_t	getRemainingBufferSize ()
	Get the size of the data remaining in the current buffer.
void	advanceBuffer (const uint64_t offset)
	Advance the current buffer by a number of bytes.
virtual size_t	nRemainingBuffers () const =0
	Get the number of remaining buffers.
virtual uint32_t	getVersion () const
virtual void	reset ()
virtual bool	getNextBuffer (const uint8_t **buffer, uint64_t *size)=0
