Constructors
CountingStreamBuf
Creates an unconnected CountingStreamBuf.
CountingStreamBuf
CountingStreamBuf(
std::istream & istr
);
Creates the CountingStreamBuf and connects it to the given input stream.
CountingStreamBuf
CountingStreamBuf(
std::ostream & ostr
);
Creates the CountingStreamBuf and connects it to the given output stream.
Destructor
~CountingStreamBuf
Destroys the CountingStream.
Member Functions
addChars
void addChars(
std::streamsize chars
);
Add to the total number of characters.
addLines
void addLines(
std::streamsize lines
);
Add to the total number of lines.
addPos
void addPos(
std::streamsize pos
);
Add to the number of characters on the current line.
chars 
std::streamsize chars() const;
Returns the total number of characters.
getCurrentLineNumber
std::streamsize getCurrentLineNumber() const;
Returns the current line number (same as lines()).
lines
std::streamsize lines() const;
Returns the total number of lines.
pos
std::streamsize pos() const;
Returns the number of characters on the current line.
reset
void reset();
Resets all counters.
setCurrentLineNumber
void setCurrentLineNumber(
std::streamsize line
);
Sets the current line number.
This is mainly useful when parsing C/C++ preprocessed source code containing #line directives.
readFromDevice 
int readFromDevice();
writeToDevice
int writeToDevice(
char c
);
