      Specified by:
      compareTo in interface Comparable<MetadataVersion>

    • isAtLeast

      public boolean isAtLeast(int major, int minor)
      Check if this version is at least (equals or higher) the one identified by major and minor versions integer literals.
      Parameters:
      major - major version
      minor - minor version
      Returns:
      true if the version is equal to or higher than the one it is being checked against

    • isEqualTo

      public boolean isEqualTo(int major, int minor)
      Check if the version is the same as the one identified by major and minor versions integer literals.
      Parameters:
      major - major version
      minor - minor version
      Returns:
      true if the version is equal to the one it is being checked against

    • isHigherThan

      public boolean isHigherThan(int major, int minor)
      Check if this version comes after the one identified by major and minor versions integer literals. That is, this one was introduced later.
      Parameters:
      major - major version
      minor - minor version
      Returns:
      true if the version is defined later than the one it is being checked against
