Constructor & Destructor Documentation

vector_bitreader::vector_bitreader (  const std::vector< char > &  _s  )  [inline]

Constructor. Sets the number of bits available to the size of the vector. Parameters: _s  - the vector to use. Definition at line 71 of file bitreaders.hpp. : bitreader(8 * _s.size()), s(_s), index(0) { ; }

vector_bitreader::vector_bitreader (  const std::vector< char > &  _s, size_t  size_in_bits )  [inline]

Constructor with size specification. Parameters: _s  - the vector to use. size_in_bits  - the number of bits available. Definition at line 76 of file bitreaders.hpp. : bitreader(size_in_bits), s(_s), index(0) { ; }

Member Function Documentation

bool vector_bitreader::supports_seek (   )  const [inline, virtual]

Check if seek functions are supported. Returns: true if seek functions are supported. Implements bitreader. Definition at line 81 of file bitreaders.hpp. { return true; }

char vector_bitreader::read_next_byte (   )  [inline, protected, virtual]

Defines the method of reading a single byte of input. Derived classes must implement this function. Returns: the next byte (8 bits) from the input. Implements bitreader. Definition at line 85 of file bitreaders.hpp. { return s[index++]; }

void vector_bitreader::set_position (  size_t  pos  )  [inline, protected, virtual]

Defines the method of setting the position for the next read. Derived classes should implement this function if possible. Parameters: pos  - the position for the next read. Reimplemented from bitreader. Definition at line 86 of file bitreaders.hpp. { index = pos; }
