Session storage by ID

4D v20 R7


Session storage by ID ( id ) -> Function result

Parameter	Type	Description
id	Text	Unique identifier (UUID) of the session on the server
Function result	Object	Storage object of the session

Note

The Session storage by ID 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 the server and is stored in the .id property of the session object. If the session does not exist on the server, 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.

Example

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

 

 $obj:=Session storage by ID($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
