def
thenCompare[A](a1: A, a2: A)(implicit ord: Ordering[A]): Int
Returns the result of the immediately previous comparison if it was not
0
; otherwise the result of comparing two other things (a1
anda2
).Returns the result of the immediately previous comparison if it was not
0
; otherwise the result of comparing two other things (a1
anda2
).This method is intended to be used to chain comparisons, as in the following example:
case class PlayingCard(rank: Rank, suit: Suit) extends Ordered[PlayingCard] { override def compare(other: PlayingCard): Int = { (this.rank compare that.rank) .thenCompare(this.suit, that.suit) } }
While this method can called on arbitrary Ints, to be meaningful, it should only be called on the result of a previous comparison.
- A
the type of
a1
anda2
- a1
the first thing to compare
- a2
the second thing to compare
- ord
an Ordering for
a1
anda2
- returns
the result of the previous comparison if it was not
0
, or the result of comparing the two other things otherwise
