      Sets the left element of this pair (optional operation).
      Specified by:
      key in interface Pair<Integer,V>
      Parameters:
      l - a new value for the left element.

    • of

      static <V> IntObjectPair<V> of(int left, V right)
      Returns a new type-specific immutable Pair with given left and right value.
      Parameters:
