Server-Side Communication ActionScript 31

The above example works, but must be executed every time a client connects. If you want the

same methods and properties to be available to all clients in the

application.clients array

without defining them every time, you must assign them to the prototype property of the Client

object There are two steps to extending a built-in class using the

prototype method. You can

write the steps in any order in your script. The following example extends the built-in Client

object, so the first step is to write the function that you will assign to the

prototype property:

// first step: write the functions

function Client_getWritePermission(){

// "writeAccess" property is already built-in to the client class

return this.writeAccess;

}

function Client_createUniqueID(){

var ipStr = this.ip;

// "ip" property is already built-in to the client class

var uniqueID = "re123mn"

// you would need to write code in the above line

// that creates a unique ID for each client instance

return uniqueID;

}

// second step: assign prototype methods to the functions

Client.prototype.getWritePermission = Client_getWritePermission;

Client.prototype.createUniqueID = Client_createUniqueID;

// a good naming convention is to start all class method

// names with the name of the class, followed by an underscore

You can also add properties to prototype, as shown in the following example:

Client.prototype.company = "Macromedia";

The methods are available to any instance, so within application.onConnect, which is passed a

clientObj argument, you can write the following code:

application.onConnect = function(clientObj){

var clientID = clientObj.createUniqueID();

var clientWritePerm = clientObj.getWritePermission();

};
