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

if (so.isDirty){

SharedObject.commit(so.name);

}

SharedObject.lock()

so.lock()

Locks a shared object. 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 through the

SharedObject.onSync() handler to all the clients that subscribe to this shared object. If you nest the

SharedObject.lock() and SharedObject.unlock() methods, make sure that there is an unlock() method for

every

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

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.
