BToAEquivalenceConstraint

final class BToAEquivalenceConstraint[A, B](equivalenceOfA: Equivalence[A], cnv: B => A) extends CanEqual[A, B]

An implementation of Constraint for two types A and B that requires an Equality[A] and a conversion function from B to A.

Value parameters:
equivalenceOfA

an Equivalence type class for A

Value members

Concrete methods

override def areEqual(a: A, b: B): Boolean

Indicates whether the objects passed as a and b are equal by returning the result of invoking areEqual(a, cnv(b)) on the passed equalityOfA object.

Indicates whether the objects passed as a and b are equal by returning the result of invoking areEqual(a, cnv(b)) on the passed equalityOfA object.

In other words, the b object of type B is first converted to an A via the passed conversion function, cnv, then compared for equality with the a object.

Value parameters:
a

a left-hand-side object being compared with another (right-hand-side one) for equality (e.g., a == b)

b

a right-hand-side object being compared with another (left-hand-side one) for equality (e.g., a == b)
