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 getClass(): Class[_]

    Definition Classes
    Any

  3. abstract def set(a: A): (Container) ⇒ 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

Concrete Value Members

    Definition Classes
    Any

  2. final def ##(): Int

    Definition Classes
    Any

  3. def :=(a: A): (Container) ⇒ Container

    alias to set

  4. final def ==(arg0: Any): Boolean

    Definition Classes
    Any

  5. final def asInstanceOf[T0]: T0

    Definition Classes
    Any

  6. 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.

  7. def equals(arg0: Any): Boolean

    Definition Classes
    Any

  8. def hashCode(): Int

    Definition Classes
    Any

  9. final def isInstanceOf[T0]: Boolean

    Definition Classes
    Any

  10. def modify(f: (A) ⇒ A): (Container) ⇒ Container

    Represent an update operator (like x.

    Represent an update operator (like x.y += 1 )

  11. def toString(): String

    Definition Classes
    Any

  12. def zip[B](other: Lens[Container, B]): Lens[Container, (A, B)]

    Given two lenses with the same origin, returns a new lens that can mutate both values represented by both lenses through a tuple.
