application.registerClass()

application.registerClass(className, constructor)

Registers a constructor function that is used when deserializing an object of a certain class type. If the constructor for

a class is not registered, you cannot call the deserialized object’s methods. This method is also used to unregister the

constructor for a class. This is an advanced use of the server and is necessary only when sending ActionScript objects

between a client and a server.

The client and the server communicate over a network connection. Therefore, if you use typed objects, each side must

have the prototype of the same objects they both use. In other words, both the client-side and Server-Side ActionScript

must define and declare the types of data they share so that there is a clear, reciprocal relationship between an object,

method, or property on the client and the corresponding element on the server. You can call

application.registerClass() to register the object’s class type on the server side so that you can use the methods

defined in the class.

Constructor functions should be used to initialize properties and methods; they should not be used for executing

server code. Constructor functions are called automatically when messages are received from the client and need to be

“safe” in case they are executed by a malicious client. You shouldn’t define procedures that could result in negative

situations, such as filling up the hard disk or consuming the processor.

The constructor function is called before the object’s properties are set. A class can define an onInitialize()

method, which is called after the object has been initialized with all its properties. You can use this method to process

data after an object is deserialized.
