ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

SharedObject.onSync()

so.onSync = function(list){}

Invoked when a shared object changes. Use the onSync() handler to define a function that handles changes made

to a shared object by subscribers.

For proxied shared objects, defines the function to get the status of changes made by the server and other subscribers.

Note: You cannot define the

onSync() handler on the prototype property of the SharedObject class in Server-Side

ActionScript.

Availability

Flash Communication Server 1

Parameters

list An array of objects that contain information about the properties of a shared object that have changed since

the last time the

onSync() handler was called. The notifications for proxied shared objects are different from the

notifications for shared objects that are owned by the local application instance. The following table describes the

codes for local shared objects:

Note: Changing or deleting a property on the server side by using the

SharedObject.setProperty() method always

succeeds, so there is no notification of these changes.

The following table describes the codes for local shared objects:

Note: The

SharedObject.onSync() handler is invoked when a shared object has been successfully synchronized with

the server. If there is no change in the shared object, the list object may be empty.

Local code Meaning

change A property was changed by a subscriber.

delete A property was deleted by a subscriber.

name The name of a property that has changed or been deleted.

oldValue The old value of a property. This is true for both change and delete messages; on the client, oldValue is

not set for delete.

Proxied code Meaning

success A server change of the shared object was accepted.

reject A server change of the shared object was rejected. The value on the remote instance was not changed.

change A property was changed by another subscriber.

delete A property was deleted. This notification can occur when a server deletes a shared object or if another

subscriber deletes a property.

clear All the properties of a shared object are deleted. This can happen when the server’s shared object is out of

sync with the master shared object or when the persistent shared object migrates from one instance to

another. This event is typically followed by a change message to restore all of the server’s shared object

properties.

name The name of a property that has changed or been deleted.

oldValue The old value of the property. This is valid only for the reject, change, and delete codes.
