<=(_:_:)
Returns a Boolean value indicating whether the first tuple is ordered before or the same as the second in a lexicographical ordering.
Declaration
func <= <A, B, C, D, E>(lhs: (A, B, C, D, E), rhs: (A, B, C, D, E)) -> Bool where A : Comparable, B : Comparable, C : Comparable, D : Comparable, E : ComparableParameters
- lhs:
A tuple of
Comparableelements. - rhs:
Another tuple of elements of the same type as
lhs.
Discussion
Given two tuples (a1, a2, ..., aN) and (b1, b2, ..., bN), the first tuple is before or the same as the second tuple if and only if a1 < b1 or (a1 == b1 and (a2, ..., aN) <= (b2, ..., bN)).
