Server-Side Communication ActionScript 49

The this keyword used in the body of the function is set to the shared object instance returned

SharedObject.get.

If you don’t want the server to receive a particular broadcast message, do not define this handler.

Example

The following example defines a handler function called broadcastMsg:

var mySO = SharedObject.get("userList", false);

mySO.broadcastMsg = function(msg1, msg2){

trace(msg1 + " : " + msg2);

}

SharedObject.lock

Availability

Flash Communication Server MX.

Usage

SharedObject.lock()

Parameters

None.

Returns

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

proxied shared objects, always returns -1.

Description

Method; locks the shared object instance. This method gives the server-side script exclusive access

to the shared object; when the

SharedObject.unlock method is called, all changes are batched

and one update message is sent to all the clients subscribed to this shared object. If you nest the

SharedObject.lock and SharedObject.unlock methods, make sure there is an unlock for

every

lock; otherwise, clients are blocked from accessing the shared object.

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

Example

This example locks the myShared shared object, executes the code that is to be inserted, and then

unlocks the object:

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

myShared.lock();

// insert code here that operates on the shared object

myShared.unlock();

SharedObject.name

Availability

Flash Communication Server MX.

Usage

SharedObject.name

Description

Property (read-only); the name of a shared object.
