WWL JS Mixin Chain

| Master | Develop | |--------|---------| | | |

The mixin chain allows to include prototypes with an undefined parent class into your classes structure.

So you can append prototypes with mixin like code by using the ext function of the mixin chain.

Mixin prototypes needs to be encapsuled inside a function getting the super class as parameter.

Example

Let's assume, we've got the following super class:

class SuperClass
  attribute1: 1
  attribute2: 2
  attribute3: 3
  getValue1: -> 1
  getValue2: -> 2
  getValue3: -> 3
  getValue4: -> 4
  @getStaticValue1: -> 1
  @getStaticValue2: -> 2
  @getStaticValue3: -> 3
  @getStaticValue4: -> 4

And then, we implemented the following mixins which are overwriting some attributes, instance functions and class functions:

MixinA = (superclass) -> class MA extends superclass
  attribute1: 10
  attribute3: 30
  getValue1: -> super() + 10
  getValue4: -> 'MixinA'
  @getStaticValue1: -> super() + 10
  @getStaticValue4: -> 'MixinA'

MixinB = (superclass) -> class MB extends superclass
  attribute2: 200
  attribute3: 300
  getValue1: -> super() + 100
  getValue2: -> super() + 100
  getValue4: -> 'MixinB'
  @getStaticValue1: -> super() + 100
  @getStaticValue2: -> super() + 100
  @getStaticValue4: -> 'MixinB'

Inherit SuperClass only

ext = require('wwl-js-mixin-chain')

class T extends ext(SuperClass).with()
t = new T()

t.attribute1          # 1
t.attribute2          # 2
t.attribute3          # 3
t.getValue1()         # 1
t.getValue2()         # 2
t.getValue3()         # 3
t.getValue4()         # 4
T.getStaticValue1()   # 1
T.getStaticValue2()   # 2
T.getStaticValue3()   # 3
T.getStaticValue4()   # 4

Inherit SuperClass with MixinA

ext = require('wwl-js-mixin-chain')

class T extends ext(SuperClass).with(MixinA)
t = new T()

t.attribute1          # 10
t.attribute2          # 2
t.attribute3          # 30
t.getValue1()         # 11
t.getValue2()         # 2
t.getValue3()         # 3
t.getValue4()         # 'MixinA'
T.getStaticValue1()   # 11
T.getStaticValue2()   # 2
T.getStaticValue3()   # 3
T.getStaticValue4()   # 'MixinA'

Inherit SuperClass with MixinB

ext = require('wwl-js-mixin-chain')

class T extends ext(SuperClass).with(MixinB)
t = new T()

t.attribute1          # 1
t.attribute2          # 200
t.attribute3          # 300
t.getValue1()         # 101
t.getValue2()         # 102
t.getValue3()         # 3
t.getValue4()         # 'MixinB'
T.getStaticValue1()   # 101
T.getStaticValue2()   # 102
T.getStaticValue3()   # 3
T.getStaticValue4()   # 'MixinB'

Inherit SuperClass with MixinA and MixinB

ext = require('wwl-js-mixin-chain')

class T extends ext(SuperClass).with(MixinA, MixinB)
t = new T()

t.attribute1          # 10
t.attribute2          # 200
t.attribute3          # 300
t.getValue1()         # 111
t.getValue2()         # 102
t.getValue3()         # 3
t.getValue4()         # 'MixinB'
T.getStaticValue1()   # 111
T.getStaticValue2()   # 102
T.getStaticValue3()   # 3
T.getStaticValue4()   # 'MixinB'

Inherit SuperClass with MixinB and MixinA

ext = require('wwl-js-mixin-chain')

class T extends ext(SuperClass).with(MixinB, MixinA)
t = new T()

t.attribute1          # 10
t.attribute2          # 200
t.attribute3          # 30
t.getValue1()         # 111
t.getValue2()         # 102
t.getValue3()         # 3
t.getValue4()         # 'MixinA'
T.getStaticValue1()   # 111
T.getStaticValue2()   # 102
T.getStaticValue3()   # 3
T.getStaticValue4()   # 'MixinA'
