Server-Side Communication ActionScript 53

SharedObject.resyncDepth

Availability

Flash Communication Server MX.

Usage

SharedObject.resyncDepth

Description

Property; an integer that indicates when the deleted properties of a shared object should be

permanently deleted. You can use this property in a server-side script to resynchronize shared

objects and to control when shared objects are deleted. The default value is infinity.

If the current revision number of the shared object minus the revision number of the deleted

property is greater than the value of

SharedObject.resyncDepth, the property is deleted. Also,

if a client connecting to this shared object has a client revision that, when added to the value of

SharedObject.resyncDepth is less than the value of the current revision on the server, all the

current elements of the client shared object are deleted and the valid properties are sent to the

client and the client receives a “clear” message.

This method is useful when you add and delete many properties and you don’t want to send too

many messages to the Flash client. Suppose a client is connected to a shared object that has 12

properties and then disconnects. After that client disconnects, other clients that are connected to

the shared object delete 20 properties and add 10 properties. When the client reconnects, it

could, for example, receive a delete message for the 10 properties it previously had and then a

change message on 2 properties. You could use

SharedObject.resyncDepth to send a “clear”

message, followed by a change message for 2 properties, which saves the client from receiving 10

delete messages.

Example

The following example resynchronizes the shared object mySO if the revision number difference is

greater than 10:

mySo = SharedObject.get("foo");

mySo.resyncDepth = 10;

SharedObject.send

Availability

Flash Communication Server MX.

Usage

SharedObject.send(methodName, [p1, ..., pN])

Parameters

methodName The name of a method on a client shared object instance. For example, if you

specify

doSomething, the client must invoke the SharedObject.doSomething method, with all

the

p1, ..., pN parameters.

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

objects. These parameters are passed to the specified

methodName when it executes on the Flash

client.
