AToBEquivalenceConstraint

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

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

Value parameters:
equivalenceOfB

an Equivalence type class for B

Value members

Concrete methods

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

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

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

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