Protected Member Functions
virtual int	overflow (int c)
	Called by the system ostream implementation when its internal buffer is filled, plus one character.
virtual int	sync ()
	Called by the system ostream implementation when the buffer should be flushed to output (for instance, on destruction).
Private Member Functions
void	write_chars (const char *start, int length)
	An internal function called by sync() and overflow() to store one or more characters written to the stream into the memory buffer.
void	set_literal_mode (bool mode)
	An internal function called to update the internal state according to the current value of the Notify::literal flag, which might or might not be set of the ostream at any time.
void	flush_data ()
	Writes the contents of _data to the actual output stream, either word-wrapped or not as appropriate, and empties the contents of _data.

Member Function Documentation

void WordWrapStreamBuf::flush_data (   )  [private]

Writes the contents of _data to the actual output stream, either word-wrapped or not as appropriate, and empties the contents of _data. Definition at line 156 of file wordWrapStreamBuf.cxx. Referenced by overflow(), and ~WordWrapStreamBuf().

int WordWrapStreamBuf::overflow (  int  c  )  [protected, virtual]

Called by the system ostream implementation when its internal buffer is filled, plus one character. Definition at line 94 of file wordWrapStreamBuf.cxx. References _data, _owner, flush_data(), Notify::get_literal_flag(), length, set_literal_mode(), and size_t.

void WordWrapStreamBuf::set_literal_mode (  bool  mode  )  [inline, private]

An internal function called to update the internal state according to the current value of the Notify::literal flag, which might or might not be set of the ostream at any time. When the literal flag is true, we should not word-wrap, so toggling this flag means we need to flush the current buffer. Definition at line 42 of file wordWrapStreamBuf.I. Referenced by overflow().

int WordWrapStreamBuf::sync (  void   )  [protected, virtual]

Called by the system ostream implementation when the buffer should be flushed to output (for instance, on destruction). Definition at line 73 of file wordWrapStreamBuf.cxx. References streamsize, and write_chars().

void WordWrapStreamBuf::write_chars (  const char *  start, int  length )  [private]

An internal function called by sync() and overflow() to store one or more characters written to the stream into the memory buffer. Definition at line 124 of file wordWrapStreamBuf.cxx. References _data, _program, and ProgramBase::show_text(). Referenced by sync(), and ~WordWrapStreamBuf().
