                      Detailed Description

                      Write text into file.

                      This class allows a comfortable output to a file only by using the elementary system calls open() / write() / close() and (optional) fsync(). The class is derived from OutputStream.

                      Constructor & Destructor Documentation

                      FileOut::FileOut ( const char *  path)
                      explicit

                      Constructor.

                      Opens the file for writing using the system call open().

                      Parameters
                      pathPath to the output file
                      virtual FileOut::~FileOut ( )
                      virtual

                      Destructor.

                      Close the output file (using the system call close())

                      Member Function Documentation

                      const char * FileOut::getPath ( )

                      Get path of the output file.

                      Returns
                      Path to output file (as defined in constructor)
                      static int FileOut::count ( )
                      static

                      Number of output files which are currently opened (with this class)

                      Returns
                      Number of active files
                      virtual void FileOut::flush ( )
                      overridevirtual

                      Write the string to the open file.

                      The implementation should only use the system calls write() and fsync().

                      Implements OutputStream.
