ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

You cannot use the SharedObject.lock() method on proxied shared objects.

Availability

Flash Communication Server 1

Returns

An integer indicating the lock count: 0 or greater indicates success; -1 indicates failure. For proxied shared objects,

always returns -1.

Example

The following example locks the

so shared object, executes the code that is to be inserted, and then unlocks the

object:

var so = SharedObject.get("foo");

so.lock();

// Insert code here that operates on the shared object.

so.unlock();

SharedObject.mark()

so.mark(handlerName, p1, ..., pN)

Delivers all change events to a subscribing client as a single message.

In a server-side script, you can call the

SharedObject.setProperty() method to update multiple shared object

properties between a call to the

lock() and unlock() methods. All subscribing clients receive a change event

notification through the

SharedObject.onSync() handler. However, because the server may collapse multiple

messages to optimize bandwidth, the

change event notifications may not be sent in the same order as they were in

the code.

Use the

mark() method to execute code after all the properties in a set have been updated. You can call the

handlerName parameter passed to the mark() method, knowing that all property changes before the mark() call

have been updated.

Availability

Flash Media Server 2

Parameters

handlerName Calls the specified handler on the client-side SharedObject instance. For example, if the

handlerName parameter is onChange, the client invokes the SharedObject.onChange() handler with all the p1,

...,pN

parameters.

Note: Do not use a built-in method name for a handler name. For example, if the handler name is

close, the

subscribing stream will be closed.

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

are passed to

handlerName when it is executed on the client.

Returns

A boolean value. Returns

true if the message can be dispatched to the client; otherwise, false.

Example

The following example calls the

mark() method twice to group two sets of shared object property updates for clients:

var myShared = SharedObject.get("foo", true);
