James Perkins commented on LOGTOOL-47:
--------------------------------------

The @FormatWith annotation already exists in JBL, [https://github.com/jboss-logging/jboss-logging/blob/master/src/main/java/org/jboss/logging/FormatWith.java]

> Sometimes the default toString is no good for formatting an argument.  We could introduce an interface into jboss-logging:
> {code}
> public interface Stringifier {
>     String toString(Object object);
> }
> {code}
> Then we could introduce the following annotation:
> {code}
> @Retention(SOURCE)
> @Target(PARAMETER)
> public @interface FormatWith {
>     Class<? extends Stringifier> value();
> }
> {code}
> Parameters so annotated will be formatted using an instance (singleton, pre-instantiated with the logger instance) of the stringifier.  Because of the method call overhead, such methods would require an explicit level check in the generated code.
