Server-Side Communication ActionScript 73

Example

This example opens a stream s and, when it is open, plays sample and records it. Because no

value is passed to the

record method, the default value, record, is passed.

// To start recording

s = Stream.get("foo");

if (s){

s.play("sample");

s.record();

}

// To stop recording

s = Stream.get("foo");

if (s){

s.record(false);

}

Stream.send

Availability

Flash Communication Server MX.

Usage

Stream.send(handlerName, [p1, ..., pN])

Parameters

handlerName Calls the specified handler in client-side ActionScript code. The handlerName

value is the name of a method relative to the subscribing Stream object. For example, if

handlerName is doSomething, the doSomething method at the stream level is invoked with all

the

p1, ..., pN parameters. Unlike the method names in Client.call and

NetConnection.call, the handler name can be only one level deep (that is, it cannot be of the

form

object/method).

Note: Do not use a built-in method name for a handler name. For example, the subscribing stream will be closed if

the handler name is close.

p1, ..., pN Parameters of any ActionScript type, including references to other ActionScript

objects. These parameters are passed to the specified handler when it is executed on the Flash

client.

Returns

A Boolean value of true if the message was sent to the client, false otherwise.

Description

Method; sends a message to all clients subscribing to the stream and the message is processed by

the handler specified on the client. Because the server has higher priority than the clients, the

server can still send a message on a stream owned by a client. Unlike the

Stream.play() method,

the server does not need to take ownership of a stream from the client in order to send a message.

After

send() is called, the client still owns the stream as a publisher.

Example

This example calls the method Test on the client-side Stream object and sends it the string

"hello world":

application.streams["foo"].send("Test", "hello world");
