        Create a version range from a string representation Some spec examples are
        • 1.0 Version 1.0
        • [1.0,2.0) Versions 1.0 (included) to 2.0 (not included)
        • [1.0,2.0] Versions 1.0 to 2.0 (both included)
        • [1.5,) Versions 1.5 and higher
        • (,1.0],[1.2,) Versions up to 1.0 (included) and 1.2 or higher
        Parameters:
        spec - string representation of a version or version range
        Returns:
        a new VersionRange object that represents the spec
        Throws:
        InvalidVersionSpecificationException

        public static VersionRange createFromVersion​(java.lang.String version)
      • restrict

        public VersionRange restrict​(VersionRange restriction)
        Creates and returns a new VersionRange that is a restriction of this version range and the specified version range.

        Note: Precedence is given to the recommended version from this version range over the recommended version from the specified version range.

        Parameters:
        restriction - the VersionRange that will be used to restrict this version range.
        Returns:
        the VersionRange that is a restriction of this version range and the specified version range.

        The restrictions of the returned version range will be an intersection of the restrictions of this version range and the specified version range if both version ranges have restrictions. Otherwise, the restrictions on the returned range will be empty.

        The recommended version of the returned version range will be the recommended version of this version range, provided that ranges falls within the intersected restrictions. If the restrictions are empty, this version range's recommended version is used if it is not null. If it is null, the specified version range's recommended version is used (provided it is non-null). If no recommended version can be obtained, the returned version range's recommended version is set to null.

        Throws:
        java.lang.NullPointerException - if the specified VersionRange is null.
