Parameters

None.

Returns

Returns true if successful; false otherwise.

Description

Method; deletes all properties and sends a “clear” event to all clients that subscribe to a persistent

shared object. The persistent data object is also removed from persistent shared object. You can

use

SharedObject.clear to detach from a shared object immediately after SharedObject.get

is invoked. You can use SharedObject.clear when you do not want to use a shared object

anymore and want to remove it from the server completely. This method lets you create shared

objects that persist only for a specified time.

Example

The following example calls the clear method on the shared object myShared:

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

var len = myShared.clear();

SharedObject.close

Availability

Flash Communication Server MX.

Usage

SharedObject.close()

Parameters

None.

Returns

Nothing.

Description

Method; detaches a reference from a shared object. A call to the SharedObject.get method

returns a reference to a shared object instance. The reference is valid until the variable that holds

the reference is no longer in use and the script is garbage-collected. To destroy a reference

immediately, you can call

SharedObject.close. You can use SharedObject.close when you

don’t want to proxy a shared object any longer.

Example

In this example, mySO is attached as a reference to shared object foo. When you call mySO.close

you detach the reference

mySO from the shared object foo.

mySO = SharedObject.get("foo");

// insert code here

mySO.close();
