PresentationModel class is a superclass for all 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.

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.
参数
destination:Object — Specifies the object defining the property to be bound to the value of sourceChain.
| |
destinationProperty:String — Specifies the name of the public property defined by the value of the
destination parameter that is 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)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.
|
ChangeWatcher — The property or property chain to be watched. At least one property name must specified in the
sourceChain argument, otherwise, a null value is returned.
