SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

A shared object property can be modified by a client between successive calls to SharedObject.getProperty() and

SharedObject.setProperty(). If you want to preserve transactional integrity, call the SharedObject.lock()

method before modifying the shared object; be sure to call

SharedObject.unlock() when you finish making

modifications. If you call

SharedObject.setProperty() without first calling SharedObject.lock(), the change is

made to the shared object, and all object subscribers are notified before

SharedObject.setProperty() returns. If

you call

SharedObject.lock() before you call SharedObject.setProperty(), all changes are batched and sent

when the

SharedObject.unlock() method is called. The SharedObject.onSync() handler on the client side is

invoked when the local copy of the shared object is updated.

Note: If only one source (whether client or server) is updating a shared object in a server-side script, you don’t need to use

the

lock() or unlock() method or the onSync() handler.

Availability

Flash Communication Server 1

Parameters

name The name of the property in the shared object.

value An ActionScript object associated with the property, or null to delete the property.

Example

The following example uses the SharedObject.setProperty() method to create the city property with the value

San Francisco. It then enumerates all the property values in a for loop and calls trace() to display the values.

myInfo = SharedObject.get("foo");

var addr = myInfo.getProperty("address");

myInfo.setProperty("city", "San Francisco");

var names = sharedInfo.getPropertyNames();

for (x in names){

var propVal = sharedInfo.getProperty(names[x]);

trace("Value of property " + names[x] + " = " + propVal);

}
