ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

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

Details

Flash Media Interactive 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.
