                          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.
