SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

If you register a class that has its prototype set to another class, you must set the prototype constructor back to the

original class after setting the prototype. The second example below illustrates this point.

Note: Client-side classes must be defined as function function_name(){}, as shown in the following examples. If not

defined in the correct way,

application.registerClass() does not identify the class when its instance passes from

the client to the server, and an error is returned.

Availability

Flash Communication Server 1

Parameters

className A string indicating the name of an ActionScript class.

constructor A constructor function used to create an object of a specific class type during object deserialization. The

name of the constructor function must be the same as

className. During object serialization, the name of the

constructor function is serialized as the object’s type. To unregister the class, pass the value

null as the constructor

parameter. Serialization is the process of turning an object into something that you can send to another computer over

the network.

Example

The following example defines a Color constructor function with properties and methods. After the application

connects, the

registerClass() method is called to register a class for the objects of type Color. When a typed object

is sent from the client to the server, this class is called to create the server-side object. After the application stops, the

registerClass() method is called again and passes the value null to unregister the class.

function Color(){

this.red = 255;

this.green = 0;

this.blue = 0;

}

Color.prototype.getRed = function(){

return this.red;

}

Color.prototype.getGreen = function(){

return this.green;

}

Color.prototype.getBlue = function(){

return this.blue;

}

Color.prototype.setRed = function(value){

this.red = value;

}

Color.prototype.setGreen = function(value){

this.green = value;

}

Color.prototype.setBlue = function(value){

this.blue = value;

}

application.onAppStart = function(){

application.registerClass("Color", Color);

};

application.onAppStop = function(){

application.registerClass("Color", null);

};
