Jobject

A class that adds properties to your class that are easily overriden and maintain direct accessors. Similiar to objective-c @property and @synthesize.

Jobject = require './'

class MyClass extends Jobject
  constructor: ()->
    @property 'name'
    @property 'title'
    @property 'author'

  title: ()->
    return 'TITLE: ' + @_title

  setAuthor: (author)->
    @_author = 'AUTHOR: ' + author

  author: ()->
    return @_author + '!!!!'


myClass = new MyClass()
myClass.name = 'Jesse Earle'
myClass.title = 'Fruit Loop'
myClass.author = 'Stephen King'

console.log(myClass.name) # Jesse earle
console.log(myClass.title) # TITLE: Fruit Loop
console.log(myClass.author) #AUTHOR: Stephen King!!!!

Features

• A simple way to attach getters and setters to your classes
• Similarity Objective-C @property and @synthesize
• Reduce redundant code
• Access properties with the simple dot syntax

Usage

Create a class that extends Jobject

class MyClass extends Jobject
  constructor: ->
    @property 'name'

This class now has the following properties:

• _name
• name

The _name property provides direct access to the value of the property.

The name property on the other hand actually points to a getter and setter function, but you still access it normally:

myClass = new MyClass()
myClass.name = 'Jesse'
console.log myClass.name # logs: Jesse

You can also give a default value to the property:

class MyClass extends Jobject
  constructor: ->
    @property 'name', 'Default'

myClass = new MyClass()
console.log myClass.name # logs: Default

If you do not provide a default value it will point to null. Note that the property will exist on the instance.

Overriding the getter and setter is simple:

class MyClass extends Jobject
  constructor: ->
    @property 'name', ''

  setName: (name)->
    @_name = '!' + name

  name: ()->
    return @_name + '!'

myClass = new MyClass()
myClass.name = 'Jesse'
console.log myClass.name # logs: !Jesse!
