        Key: JAMES-101
    Summary: Attributes on Mail needed
       Type: Bug

     Status: Closed
 Resolution: FIXED

    Project: James
 Components: 
             Mailet API
   Versions:
             2.1

Platform: All

Description:
Hi,  
  
What I propose is to extend the Mail interface in the Mailet SDK with the  
following methods:  
 
Object getAttribute(String name);  
Iterator getAttributeNames();  
void removeAttribute(String name);  
void setAttribute(String name, Object object);  
 
The reason is that it will allow Mailet developers to pass, Mail processing 
information between different Mailets which are related to the particular Mail 
in question and not the common context for the Mailets. If you now register 
such mail related attributes in the MailetContext, you will get yourself into 
trouble when several Mails are processed in different threads by different 
Mailets. 
 
The Mail object actually acts as a sort of Session object, but a developer 
cannot register anything on this Session. 
 
This change will also put the Mailet api more in line with the Servlet api, 
which allows setting of attributes on bothe the ServletContext and the 
HttpSession. 
 
Regards 
  Søren 
 
P.S. I will be implementing this, so I will be happy to contribute, if this 
proposal gets approved.
