Server-Side ActionScript Language Reference

Example

The following example calls the

SharedObject.send() method to invoke the doSomething() method on the client

and passes the string

"This is a test":

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

so.send("doSomething", "This is a test");

The following example is the client-side ActionScript code that defines the doSomething() method:

nc = new NetConnection();

nc.connect("rtmp://www.adobe.com/someApp");

var so = SharedObject.getRemote("foo", nc.uri, true);

so.connect(nc);

so.doSomething = function(str) {

// Process the str object.

};

SharedObject.setProperty()

so.setProperty(name, value)

Updates the value of a property in a shared object.

The

name parameter on the server side is the same as an attribute of the data property on the client side. For example,

the following two lines of code are equivalent; the first line is Server-Side ActionScript and the second is client-side

ActionScript:

so.setProperty(nameVal, "foo");

clientSO.data[nameVal] = "foo";

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.

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");
