Description
The Session storage command returns the storage object of the session whose unique identifier you passed in the id parameter.
In id, pass the UUID of the session for which you want to get the storage. It is automatically assigned by 4D (4D Server or, for standalone sessions, 4D single-user) and is stored in the .id property of the session object. If the session does not exist, the command returns Null.
Note: You can get the session identifiers using the Process activity command.
The returned object is the .storage property of the session. It is a shared object used to store information available to all processes of the session.
Exemple
This method modifies the value of a "settings" property stored in the storage object of a specific session:
//Set storage for a session
//The "Execute On Server" method property is set
#DECLARE($id : Text; $text : Text)
var $obj : Object
$obj:=Session storage($id)
If($obj.settings=Null)
Use($obj)
$obj.settings:=New shared object("text";$text)
End use
Else
Use($obj.settings)
$obj.settings.text:=$text
End use
End if
