- This implementation delegates to
Pair.left(Object)
.
-
first

of
Returns a new type-specific immutablePair
with given left and right value.- Parameters:
left
- the left value.right
- the right value.
-
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.
