Abstract Value Members

  1. abstract def get(c: Container): A

    get knows how to extract some field of type A from a container

  2. abstract def set(a: A): Mutation[Container]

    Represents an assignment operator.

    Represents an assignment operator.

    Given a value of type A, sets knows how to transform a container such that a is assigned to the field.

    We must have get(set(a)(c)) == a

  7. def compose[B](other: Lens[A, B]): Lens[Container, B]

    Composes two lenses, this enables nesting.

    Composes two lenses, this enables nesting.

    If our field of type A has a sub-field of type B, then given a lens for it (other: Lens[A, B]) we can create a single lens from Container to B.

  18. def setIfDefined(aOpt: Option[A]): Mutation[Container]

    Optional assignment.

    Optional assignment.

    Given a Some[A], assign the Some's value to the field. Given None, the container is unchanged.
