Member Function Documentation

Read()

template<typename IStream >

uint64_t BitStreamReader< IStream >::Read ( int  nbits )

inline

Read the specified number of bits from the stream.

The data is returned in the nbits least significant bits of a 64-bit uint.

Member Data Documentation

m_buffer

template<typename IStream >

uint8_t BitStreamReader< IStream >::m_buffer {0}

private

Buffered byte read in from the input stream.

A new byte is read into the buffer when m_offset reaches 8.

Definition at line 431 of file streams.h.

m_istream

template<typename IStream >

IStream& BitStreamReader< IStream >::m_istream

private

Definition at line 427 of file streams.h.

m_offset

template<typename IStream >

int BitStreamReader< IStream >::m_offset {8}

private

Number of high order bits in m_buffer already returned by previous Read() calls.

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