The PresentationModel class is a superclass for all of the presentation models. The class holds the common functionality and convenience methods that are needed to implement a presentation model, which is designed to support a specific view. A presentation model separates the behavior of a screen from the user interface controls and events. This separation simplifies the view and allows the view to make data bindings to properties in the presentation model and make simple method calls to the presentation model.

Public Methods
 MethodDefined By
 Inherited
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.
EventDispatcher
  
bindProperty(destination:Object, destinationProperty:String, source:Object, sourceChain:Object, commitOnly:Boolean = false):ChangeWatcher
Binds a public property on the destination object from a property or property chain on the source object.
PresentationModel
 Inherited
dispatchEvent(event:Event):Boolean
Dispatches an event into the event flow.
EventDispatcher
  
getCSSStyle(declaration:String, styleProperty:String, defaultValue:Object = null):Object
Returns the corresponding cascading style sheet (CSS) property to use based on the specified parameters.
PresentationModel
 Inherited
hasEventListener(type:String):Boolean
Checks whether the EventDispatcher object has any listeners registered for a specific type of event.
EventDispatcher
 Inherited
hasOwnProperty(name:String):Boolean
Indicates whether an object has a specified property defined.
Object
  
initialize():void
Subclasses can override this method, which initializes the presentation model after the view bindings have been processed to prevent view bindings from overriding the initial model state.
PresentationModel
 Inherited
isPrototypeOf(theClass:Object):Boolean
Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.
Object
 Inherited
propertyIsEnumerable(name:String):Boolean
Indicates whether the specified property exists and is enumerable.

 Inherited
removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void
Removes a listener from the EventDispatcher object.
EventDispatcher

setPropertyIsEnumerable(name:String, isEnum:Boolean = true):void
Sets the availability of a dynamic property for loop operations.

toString():String
Returns the string representation of the specified object.

 Inherited
valueOf():Object
Returns the primitive value of the specified object.

willTrigger(type:String):Boolean
Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type.

Property Detail
sessionproperty
session:SessionMap  [read-write]

A SessionMap object that stores information relating to the server session.


Implementation
    public function get session():SessionMap
    public function set session(value:SessionMap):void
stateproperty 
state:String  [read-only]

The name of the state the current view is in. The state is typically bound to the 'currentState' property of a control.

This property can be used as the source for data binding.


Implementation
    public function get state():String
Method Detail
bindProperty()method
public function bindProperty(destination:Object, destinationProperty:String, source:Object, sourceChain:Object, commitOnly:Boolean = false):ChangeWatcher

Binds a public property on the destination object from a property or property chain on the source object. This method simplifies the use of the standard BindingUtils.bindProperty method.

Parameters

destination:Object — Specifies the object defining the property to be bound to sourceChain.
 
destinationProperty:String — Specifies the name of the public property defined in the destination parameter to be bound.
 
source:Object — Specifies the object that hosts the property or property chain to be watched.
 
sourceChain:Object — Specifies the property or property chain to be watched.
 
commitOnly:Boolean (default = false) — A flag that specifies whether the handler is called for committing and noncommitting change events. A value of true specifies that the handler is called only on committing change events. A value of false specifies that the handler is called on both committing and noncommitting change events.

Returns
ChangeWatcher — A ChangeWatcher object if at least one property name has been specified in the sourceChain argument. Otherwise, a null value is returned.

getCSSStyle()method 
public function getCSSStyle(declaration:String, styleProperty:String, defaultValue:Object = null):Object

Returns the corresponding cascading style sheet (CSS) property to use based on the specified parameters.

Parameters

declaration:String — Specifies the name of the CSS selector.
 
styleProperty:String — Specifies the name of the CSS property.
 
defaultValue:Object (default = null) — Specifies the CSS property that is used if the CSS property specified by the the styleProperty parameter is not found.

Returns
Object — The CSS style
initialize()method 
public function initialize():void

Subclasses can override this method, which initializes the presentation model after the view bindings have been processed to prevent view bindings from overriding the initial model state.

setState()method 
protected function setState(newState:String):void

Sets the 'state' property to a new value and causes a PropertyChangeEvent event.

Parameters

newState:String — Specifies the new state name.
