SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

permanent One of the following values: true, false, or null. Makes a property permanent (nondeletable) if true

or deletable if

false; a null value leaves this attribute unchanged. Any attempt to delete a permanent property (by

calling

deleteobj.prop) is ignored.

Example

The following code prevents the resolve() method from appearing in enumerations:

Object.prototype.__resolve = function(methodName){ ... };

setAttributes(Object.prototype, "__resolve", false, null, null);

The following example creates three constants on a Constants object and makes them permanent and read-only:

Constants.KILO = 1000;

setAttributes(Constants, "KILO", null, true, true);

Constants.MEGA = 1000*Constants.KILO;

setAttributes(Constants, "MEGA", null, true, true);

Constants.GIGA = 1000*Constants.MEGA; setAttributes(Constants, "GIGA", null, true, true);

setInterval()

setInterval(function, interval[, p1, ..., pN])

setInterval(object.method, interval[, p1, ..., pN])

Calls a function or method at a specified time interval until the clearInterval() method is called. This method

allows a server-side script to run a routine. The

setInterval() method returns a unique ID that you can pass to the

clearInterval() method to stop the routine.

Note: Standard JavaScript supports an additional usage for the setInterval() method,

setInterval(stringToEvaluate, timeInterval), which is not supported by Server-Side ActionScript.

Availability

Flash Communication Server 1

Parameters

function A Function object.

object.method A method to call on object.

interval A number indicating the time in milliseconds between calls to function.

p1, ..., pN Optional parameters passed to function.

Returns

An integer that provides a unique ID for this call. If the interval is not set, returns -1.

Example

The following example uses an anonymous function to send the message "interval called" to the server log every

second:

setInterval(function(){trace("interval called");}, 1000);

The following example also uses an anonymous function to send the message “interval called” to the server log every

second, but it passes the message to the function as a parameter:

setInterval(function(s){trace(s);}, 1000, "interval called");

The following example uses a named function,

callback1()

, to send the message

"interval called"

to the server log:

1 2 3 4 5 6 7 8 9 10 11 12 13 ... 171 172
