AbtractObject

AbstractObject with Object State Supports and free method provides.

The derived class should overwrite the initialize and finalize methods.

Changes

V2.1.x

• add the state-able ability to any class.

• move RefObject to ref-object

• decoupled the @crabas0npm/corporis-consequatur-dolorem completely.
• All parts can be used individually.
  • stateable = require('@crabas0npm/corporis-consequatur-dolorem/ability')
  • eventable = require('events-ex/eventable')
  • refCountable = require('ref-object/ability')

V2.x

• separate eventable from AbstractObject
  • the new EventableObject can be as [email protected]
• separate eventable from RefObject too
  • the new EventableRefObject can be as [email protected]

• add the eventable function to eventable any class('@crabas0npm/corporis-consequatur-dolorem/eventable').
  • use the eventable plugin(events-ex) to implement eventable object.

• move all util functions to util-ex
• move enhanced inheritance Functions to inherits-ex.
• move AbstractError to abstract-error

V1.x

• AbstractObject inherits from EventEmitter.
• RefObject inherits from AbstractObject
• AbstractError

State-able Ability(V2.1.x)

add the Object State Supports and free method to your class directly.

stateable = require '@crabas0npm/corporis-consequatur-dolorem/ability'

module.exports = class AbstractObject
  stateable AbstractObject

Note: the eventable ability must be after the stateable. like this:

stateable = require '@crabas0npm/corporis-consequatur-dolorem/ability'
eventable = require 'events-ex/ability'

class MyObject
  stateable MyObject
  eventable MyObject # MUST BE after stateable

AbstractObject

• Methods:

  • create(class, ...): the create class method uses to create a new object instance(the util.createObject is the same function).
    • class: the class constructor to create a new instance.
    • ...: the left arguments will be passed into the class constructor.
  • createWith(class, arguments): the createWith class method uses to create a new object instance(the util.createObjectWith is the same function).
    • class: the class constructor to create a new instance.
    • arguments (array): the arguments will be passed into the class constructor.
  • initialize(...): abstract initialization method after a new instance creating.
    • ...: the constructor's arguments should be passed into initialize method.
  • finalize(...): abstract finalization method before the instance destroying.
    • ...: the free(destroy)'s arguments should be passed into finalize method.
  • (deprecated) init(...): abstract initialization method after a new instance creating.
    • init method is deprecated, pls use initialize method instead
    • ...: the constructor's arguments should be passed into init method.
  • (deprecated) final(...): abstract finalization method before the instance destroying.
    • final method is deprecated, pls use finalize instead
    • ...: the free(destroy)'s arguments should be passed into final method.
  • free(...): free the class instance.
    • ...: optional arguments will be passed into final method to process.
  • isIniting(), isInited(),isDestroying(), isDestroyed() object state testing methods:
    • to test object state

• only for EventableObject:

  • Methods:
    • dispatch(event, args[, callback]): dispath an event or callback
      • event: the event name
      • args: the args are passed to event or callback
      • callback: optional, it will not dispatch event if the callback is exists, unless the callback return false.
    • dispatchError(error[, callback]):
      • error: the error instance.
      • callback: optional, it will not dispatch 'error' event if the callback is exists, unless the callback return false.
  • Events:
    • 'initing': emit before the initialize method
    • 'inited': emit after the initialize method
    • 'destroying': emit before the finalize method
    • 'destroyed': emit after the finalize method

RefObject

RefObject has moved to ref-object

The RefObject is derived from AbstractObject. and add the RefCount and AddRef/Release Supports.

• methods:
  • release()/free(): Decrements reference count for this instance. If it is becoming less than 0, the object would be (self) destroyed.
  • addRef(): Increments the reference count for this instance and returns the new reference count.

Usage:

AbstractObject = require('@crabas0npm/corporis-consequatur-dolorem')
inherits = require('inherits-ex')
createObject = AbstractObject.create
#or createObject = require('inherits-ex/lib/createObject')

class MyObject
  inherits MyObject, AbstractObject
  initialize: (@a, @b)->
    @cache = {}
  finalize: ->
    @cache = null

myObj = createObject(MyObject, 1, 2)

# if you do not wanna use `AbstractObject.create`, you MUST remember this:
# even the constructor is empty, you should call the parent's constructor manually.
# myObj = new MyObject()

class MyObject
  inherits MyObject, RefObject
  constructor: ->
    # must call super method here:
    super
  initialize: (@a,@b)->
    @cache = {}
  finalize: ->
    @cache = null

the javascript:

var AbstractObject = require('@crabas0npm/corporis-consequatur-dolorem')
var RefObject = require('ref-object')
var inherits = require('inherits-ex')
var createObject = AbstractObject.create
//or var createObject = require('inherits-ex/lib/createObject')

//if you do not wanna to use the 'AbstractObject.create'(createObject):
var MyObject = function() {
  //super call
  MyObject.__super__.constructor.apply(this, arguments);
}
// or, this MUST use the 'AbstractObject.create'(createObject)
var MyObject = function(){}


inherits(MyObject, RefObject)


MyObject.prototype.initialize = function(a,b) {
  this.a = a
  this.b = b
  this.cache = {}
}

MyObject.prototype.finalize = function() {
  this.cache = null
}

var myObj = createObject(MyObject, 1, 2)
//or this,  must overwrite the constructor and call the super constructor.
var myObj = new MyObject(1,2)

AbstractError Classes

It has moved to abstract-error.

Enhanced Inheritance Functions

Moved to inherits-ex.

Util Functions

Moved to util-ex.
