      • eq

        public boolean eq​(Interval interval)
        It checks equality between intervals.
        Parameters:
        interval - the inerval to which the comparison is made.
        Returns:
        true if an input interval is equal to this one.
      • max

        public int max()
        It returns the right bound of the interval (maximum value).
        Returns:
        the maximal value from the interval.
      • min

        public int min()
        It returns the left range of the interval (minimum value).
        Returns:
        the minimal value from the interval.
      • singleton

        public boolean singleton()
        It checks if an intervals contains only one value (singleton).
        Returns:
        true if domain has only one value.
      • singleton

        public boolean singleton​(int c)
        It checks if an intervals contains only value c.
        Parameters:
        c - integer value to which the singleton is compared to.
        Returns:
        true if variable has a singleton domain and it is equal to value c.
