      • copyDirectoryNonCVS

        public static final void copyDirectoryNonCVS​(java.io.File from,
                                             java.io.File to)

        Copy an entire directory from one location to another, skipping CVS directories. Note that this will silently overwrite old files, just like copyFile().
        Parameters:

        to - Destination directory, i.e. the 'new name' of the copy of the from directory.

      • compareDirsText

        public static java.lang.String compareDirsText​(java.io.File fstDir,
                                               java.io.File sndDir)
                                        throws IOFailure
        Compares the content of two directories and report all differences in the returned text string. If no difference are located, an empty string ("") is returned. All files located in the directories are treated as text files, and a text comparison is done on a line by line basis. This function will not work if the dirs contain binary files. No attempt is made to recover from errors.
        Parameters:
        fstDir - The directory to compare with sndDir
        sndDir - The directory to compare with fstDir
        Returns:
        A text string describing the differences between the two dirs. Empty if no differences are found.
        Throws:
        IOFailure - if there are problems reading the content of the dirs.

      • getDifferences

        Return textual description of the differences between two strings.
        Parameters:
        s1 - strings to compare
