ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

Parameters

name A string; identifies the header and the ActionScript object data associated with it.

mustUnderstand A boolean; true indicates that the server must understand and process this header before it

handles any of the following headers or messages.

object An Object.

Example

The following example creates a new NetConnection instance,

nc, and connects to an application at web server

www.foo.com that is listening at port 1929. This application dispatches the service /blag/SomeCoolService. The last

line of code adds a header called

foo.

nc=new NetConnection();

nc.connect("http://www.foo.com:1929/blag/SomeCoolService");

nc.addHeader("foo", true, new Foo());

NetConnection.call()

nc.call(methodName, [resultObj [, p1, ..., pN])

Invokes a command or method on another Flash Media Server or an application server to which the application

instance is connected. The

NetConnection.call() method on the server works the same way as the

NetConnection.call() method on the client: it invokes a command on a remote server.

Note: To call a method on a client from a server, use the

Client.call() method.

Availability

Flash Communication Server 1

Parameters

methodName A string indicating a method specified in the form "[objectPath/]method". For example, the

someObj/doSomething command tells the remote server to invoke the clientObj.someObj.doSomething()

method, with all the

p1, ..., pN parameters. If the object path is missing, clientObj.doSomething() is invoked

on the remote server.

resultObj An Object. This optional parameter is used to handle return values from the server. The result object

can be any object that you defined and can have two defined methods to handle the returned result:

onResult()

and

onStatus(). If an error is returned as the result, onStatus() is invoked; otherwise, onResult() is invoked.

p1, ..., pN Optional parameters that can be of any ActionScript type, including a reference to another Action-

Script object. These parameters are passed to the

methodName parameter when the method is executed on the remote

application server.

Returns

For RTMP connections, returns a boolean value of

true if a call to methodName is sent to the client; otherwise,

false. For application server connections, it always returns true.

Example

The following example uses RTMP to execute a call from one Flash Media Server to another Flash Media Server. The

code makes a connection to the App1 application on server 2 and then invokes the

Sum() method on server 2:

nc1.connect("rtmp://server2.mydomain.com/App1", "svr2",);

nc1.call("Sum", new Result(), 3, 6);
