        Description copied from interface: Pair
        Sets the left element of this pair (optional operation).
        Specified by:
        key in interface Pair<java.lang.Double,​V>
        Parameters:
        l - a new value for the left element.
      • of

        static <V> DoubleObjectPair<V> of​(double left,
                                          V right)
        Returns a new type-specific immutable Pair with given left and right value.
        Parameters:
        left - the left value.
        right - the right value.
      • lexComparator

        static <V> java.util.Comparator<DoubleObjectPair<V>> lexComparator()
        Returns a lexicographical comparator for pairs.

        The comparator returned by this method implements lexicographical order. It compares first the left elements: if the result of the comparison is nonzero, it returns said result. Otherwise, this comparator returns the result of the comparison of the right elements.

        Returns:
        a lexicographical comparator for pairs.
