Member Function Documentation

Flush()

template<typename OStream >

void BitStreamWriter< OStream >::Flush ( )

inline

Flush any unwritten bits to the output stream, padding with 0's to the next byte boundary.

Definition at line 371 of file streams.h.

Here is the caller graph for this function:

Write()

template<typename OStream >

void BitStreamWriter< OStream >::Write ( uint64_t  data, int  nbits  )

inline

Write the nbits least significant bits of a 64-bit int to the output stream.

Data is buffered until it completes an octet.

Member Data Documentation

m_buffer

template<typename OStream >

uint8_t BitStreamWriter< OStream >::m_buffer {0}

private

Buffered byte waiting to be written to the output stream.

The byte is written buffer when m_offset reaches 8 or Flush() is called.

Definition at line 333 of file streams.h.

m_offset

template<typename OStream >

int BitStreamWriter< OStream >::m_offset {0}

private

Number of high order bits in m_buffer already written by previous Write() calls and not yet flushed to the stream.

The next bit to be written to is at this offset from the most significant bit position.

Definition at line 338 of file streams.h.

m_ostream

template<typename OStream >

OStream& BitStreamWriter< OStream >::m_ostream

private

Definition at line 329 of file streams.h.
