class-delegator v0.0.3

ClassDelegator

Delegates class methods to a member instance.
Designed for use with CoffeeScript classes, but JavaScript should work too!

Example

# ClassDelegator provides `delegate` as a static method.
{delegate} = require 'class-delegator'

# Ducks go quack!
class Duck
  quack: ->
    console.log 'quack!'

# Pets delegates Duck behavior to the `duck` member instance.
class Pets
  delegate @, 'duck', Duck
  constructor: ->
    @duck = new Duck()

# Create a new pets instance (with duck member).
pets = new Pets()

# Pets leaves the quacking to the duck!
pets.quack()

Install

$ npm install 'class-delegator'
