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

filename A string indicating the relative path to a script file from the main.asc file.

Example

The following example loads the myLoadedFile.asc file:

load("myLoadedFile.asc");

protectObject()

protectObject(object)

Protects the methods of an object from application code. Application code cannot access or inspect the methods

directly. You can use this function only in the secure.asc file.

Availability

Flash Media Server 2

Parameters

object An object to protect.

Returns

An Object.

Details

After an object is protected, don’t reference it in global variables or make it a member of an accessible object. The object

returned by

protectObject() dispatches all method invocations to the underlying object but blocks access to

member data. As a result, you can’t enumerate or modify members directly. The protected object keeps an outstanding

reference to the underlying object, which ensures that the object is valid. The protected object follows normal reference

rules and exists while it is referred to.

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.

Example

After secure.asc is executed, calls to load() are directed through the user-defined system call, as shown in the

following example:

1 2 3 4 5 6 7 8 9 10 11 ... 171 172
