        public static int compareVersion​(java.lang.String version)
        Compares the given version String to the current version of JaxoDraw. See compareVersions for a specification of a valid version String.
        Parameters:
        version - the version to compare to. If this is null, +1 is returned, ie the current version is assumed greater.
        Returns:
        0 if the two versions are equal, a value less than 0 if the current version is smaller than the given one, a value greater than 0 if the current version is greater than the given one,

      • compareVersions

        public static int compareVersions​(java.lang.String v1,
                                  java.lang.String v2)
        Compares two version Strings.

        A valid version String must be of the form

        major.minor[.bugfix][-qualifier]

        where the quantities in square brackets are optional. The major, minor and bugfix parts have to be non-negative integers.

        For the comparison, the major, minor and bugfix arguments are compared as integers in this order. The first ocurring inequality is returned. A missing bugfix counts as 0.

        If all integers are equal, the qualifiers are compared lexigraphically as Strings. If one version has a qualifier while the other has none, the version with the qualifier is considered smaller.

        Examples:

        3.0.1 > 2.10.221
        3.0-SNAPSHOT < 3.0
        2.1.0 == 2.1
        1.2.3-abc < 1.2.3-xyz
        Parameters:
        v1 - the first version to compare. Cannot be null.
        v2 - the second version to compare. Cannot be null.
        Returns:
        0 if the two versions are equal, a value less than 0 if v1 is smaller than v2, a value greater than 0 if v1 is greater than v2.
