      • -1 if this version is older than other
      • 0 if both versions are equal
      Specified by:
      compareTo in interface Comparable<Version>

    • isAtLeast

      public boolean isAtLeast(Version other)

    • isNewerThan

      public boolean isNewerThan(Version other)

    • isUnknown

      public boolean isUnknown()

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • hashCode

      Overrides:
      toString in class Object

    • parse

      public static Version parse(String versionString)
      Parses a version number from the specified version string. An empty string will return UNKNOWN. A non-empty string that is not a valid version number will result in an exception.
      Throws:
      IllegalArgumentException - if the version string cannot be parsed.

    • canParse

      public static boolean canParse(String versionString)
      Returns true if versionString represents a version number that can be represented by this class. In other words, this method indicates whether parse(String) will throw an exception if invoked with versionString.
