                              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.
