abstract def get(c: Container): A

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

abstract def getClass(): Class[_]

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

Represents an assignment operator.

final def !=(arg0: Any): Boolean

final def ##(): Int

def :=(a: A): Mutation[Container]

alias to set

final def ==(arg0: Any): Boolean

final def asInstanceOf[T0]: T0

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

Composes two lenses, this enables nesting.

def equals(arg0: Any): Boolean

def hashCode(): Int

final def isInstanceOf[T0]: Boolean

def modify(f: (A) ⇒ A): Mutation[Container]

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

def toString(): String

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.
