API

Respict(data, parent)

var parent = new Respict({a: 1})
var child = new Respict({b: 2}, parent)
child.data // => {b: 2}
child.parent // => parent

Respict#set(key, value)

rebind key to value. If key is not allready bound anywhere in the parent hierachy a new binding will be created on this dictionary.

child.set('a', 3) // => 3
parent.data // => {a: 3}
child.set('c', 4) // => 4
child.data // => {b:2, c:4}

Respict#get(key, fallback)

get the value bound to key

child.get('a') // => parent.get('a')
parent.get('a') // => 3

Respict#has(key)

check if key is bound on this dictionary or one of its parents

child.has('a') // => true
child.has('b') // => true
child.has('c') // => true
child.has('d') // => false

Respict#create(key)

create key on this dictionary even if it already exists on a parent.

child.data // => {b:2, c:4}
child.create('a', 1)
child.data // => {a:1, b:2, c:4}
child.get('a') // => 1
parent.get('a') // => 3
