Mikael Ståldal commented on LOG4J2-1161:
----------------------------------------

The "with" method need to be in each subclass in order to return the correct 
type. If only in MapMessage, then this will not work:

{code}
    StructuredDataMessage msg = new StructuredDataMessage(confirm, null, 
"transfer")
            .withValue("toAccount", toAccount)
            .withValue("fromAccount", fromAccount)
            .withValue("amount", amount);
{code}

> It would be nice to have a builder like pattern to add values to 
> {{MapMessage}} and its subclass {{StructuredDataMessage}}, so you can do 
> {code}
>         EventLogger.logEvent(
>             new StructuredDataMessage(confirm, null, "transfer")
>                 .withValue("toAccount", toAccount)
>                 .withValue("fromAccount", fromAccount)
>                 .withValue("amount", amount)
>         );
> {code}
> instead of
> {code}
>         StructuredDataMessage msg = new StructuredDataMessage(confirm, null, 
> "transfer");
>         msg.put("toAccount", toAccount);
>         msg.put("fromAccount", fromAccount);
>         msg.put("amount", amount);
>         EventLogger.logEvent(msg);
> {code}
