[jboss-jira] [JBoss JIRA] (LOGTOOL-55) Introduce "transformation" annotations

David Lloyd created LOGTOOL-55: ---------------------------------- Summary: Introduce "transformation" annotations Key: LOGTOOL-55 URL: https://issues.jboss.org/browse/LOGTOOL-55 Project: Log Tool Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: David Lloyd Assignee: David Lloyd Priority: Optional It would be nice to be able to introduce transformations which are applied to method parameters, like this: {code} @Message(id = 1234, value = "This is a bad %s") IllegalStateException badType(@Transform(GET_CLASS) Object thing); {code} ...where {{GET_CLASS}} comes from an enum of predefined transformations. The resultant code would replace {{thing}} in the final rendering with {{thing == null ? null : thing.getClass()}}. It might make sense to support multiple transforms too: {code} @Message(value = "The class' hash is %x") String hashWoo(@Transform({GET_CLASS, HASH_CODE}) Object thing); {code} in which case the transforms would be applied in order. Some transform ideas: * {{GET_CLASS}} -> {{x == null ? null : x.getClass()}} * {{HASH_CODE}} -> {{x == null ? 0 : x.hashCode()}} * {{IDENTITY_HASH_CODE}} -> {{x == null ? 0 : System.identityHashCode(x)}} * {{SIZE}} -> depending on type, choose String.length(), array.length, Collection/Map.size() -- This message is automatically generated by JIRA.
