final class AToBEquivalenceConstraint[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.

  1. new AToBEquivalenceConstraint(equivalenceOfB: Equivalence[B], cnv: (A) => B)

    equivalenceOfB

    an Equivalence type class for B

Value Members

  1. 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.

    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)
