traitEquiv[T] extendsSerializable
A trait for representing equivalence relations. It is important to distinguish between a type that can be compared for equality or equivalence and a representation of equivalence on some type. This trait is for representing the latter.
Anequivalence relation is a binary relation on a type. This relation is exposed as theequiv method of theEquiv trait. The relation must be:
reflexive:
equiv(x, x) == truefor any x of typeT.symmetric:
equiv(x, y) == equiv(y, x)for anyxandyof typeT.transitive: if
equiv(x, y) == trueandequiv(y, z) == true, thenequiv(x, z) == truefor anyx,y, andzof typeT.
