        public static void copyFile​(java.lang.String filename1,
                                    java.lang.String filename2)
                             throws java.io.IOException
        Copy filename1 into filename2 (mkdirs for filename2)
        Parameters:
        filename1 - the source file

      • copyFile

        public static void copyFile​(java.io.File f1,
                                    java.io.File f2)
                             throws java.io.IOException
        Copy f1 into f2 (mkdirs for f2). This method is about 25% faster than IOUtil.copyFile()
        Parameters:
        f1 - the source file
        f2 - the target file
        Throws:
        java.io.IOException

      • goToLine

        public static boolean goToLine​(java.nio.ByteBuffer buffer,
                                       long line)
        Move the position of the given ByteBuffer to the given line.
        Parameters:
        buffer - the buffer to move the position.
        line - the line to be reached
        Returns:
        true if the line has been reached, false otherwite (line out of buffer size)
