SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

Availability

Flash Communication Server 1

Parameters

intervalID An identifier that contains the value returned by a previous call to the setInterval() method.

Example

The following example creates a function named callback() and passes it to the setInterval() method, which is

called every 1000 milliseconds and outputs the message

"interval called." The setInterval() method returns a

number that is assigned to the intervalID variable. The identifier lets you cancel a specific setInterval() call. In the

last line of code, the

intervalID variable is passed to the clearInterval() method to cancel the setInterval() call.

function callback(){trace("interval called");}

var intervalID;

intervalID = setInterval(callback, 1000);

// sometime later

clearInterval(intervalID);

getGlobal()

Provides access to the global object from the secure.asc file while the file is loading. Use the getGlobal() function to

create protected system calls.

Availability

Flash Media Server 2

Details

Adobe Media Server has two script execution modes: secure and normal. In secure mode, only the secure.asc file (if it

exists) is loaded and evaluated—no other application scripts are loaded. The

getGlobal() and protectObject()

functions are available only in secure mode. These functions are very powerful because they provide complete access

to the script execution environment and let you create system objects. Once the secure.asc file is loaded, the server

switches to normal script execution mode until the application is unloaded.

To prevent inadvertent access to the global object, always hold its reference in a temporary variable (declared by var);

do not hold its reference in a member variable or a global variable.

Example

The following code gets a reference to the global object:

var global = getGlobal();

load()

load(filename)

Loads a Server-Side ActionScript file (ASC) or JavaScript file (JS) into the main.asc file. Call this function to load

ActionScript libraries. The loaded file is compiled and executed after the main.asc file is successfully loaded, compiled,

and executed, but before

application.onAppStart() is called. The path of the specified file is resolved relative to

the main.asc file.
