Member Functions

getNewLine

const std::string & getNewLine() const;

Returns the line ending currently in use.

setNewLine

void setNewLine(
    const std::string & newLineCharacters
);

Sets the target line ending for the converter.

Possible values are:

  • NEWLINE_DEFAULT (whatever is appropriate for the current platform)
  • NEWLINE_CRLF (Windows),
  • NEWLINE_LF (Unix),
  • NEWLINE_CR (Macintosh)

In theory, any character sequence can be used as newline sequence. In practice, however, only the above three make sense.

int readFromDevice();

writeToDevice protected

int writeToDevice(
    char c
