addProperty (Object.addProperty method)

public addProperty(name:String, getter:Function, setter:Function) : Boolean
Creates a getter/setter property. When Flash reads a getter/setter property, it invokes the
function, and the function's return value becomes the value of
getter/setter property, it invokes the
a property with the given name already exists, the new property overwrites it.
A "get" function is a function with no parameters. Its return value can be of any type. Its type
can change between invocations. The return value is treated as the current value of the
property.
A "set" function is a function that takes one parameter, which is the new value of the property.
For example, if property
parameter of type number. The return value of the set function is ignored.

You can add getter/setter properties to prototype objects. If you add a getter/setter property to
a prototype object, all object instances that inherit the prototype object inherit the getter/
setter property. This makes it possible to add a getter/setter property in one location, the
prototype object, and have it propagate to all instances of a class (similar to adding methods to
prototype objects). If a get/set function is invoked for a getter/setter property in an inherited
prototype object, the reference passed to the get/set function is the originally referenced
object--not the prototype object.
