Mikael Ståldal commented on LOG4J2-1255:
----------------------------------------
I am looking at how to do this in the Scala API I am working on. What about
this:
(Quick Scala intro: types goes after variables/methods/parameters, {{Unit}} is
like {{void}} in Java, {{AnyRef}} is like {{Object}} in Java, the {{*}} is
varargs)
{code}
class Logger(val delegate: ExtendedLogger) {
// other stuff...
def traceEntry(): EntryMessage = delegate.traceEntry()
def traceEntry(params: AnyRef*): EntryMessage =
delegate.traceEntry(null, params) // TODO this should be a macro to avoid
varargs array creation when trace is not enabled
def traceEntry(message: Message): EntryMessage = delegate.traceEntry(message)
def traceExit[R](result: R): R = delegate.traceExit(result)
def traceExit(): Unit = delegate.traceExit()
def traceExit(entryMessage: EntryMessage): Unit =
delegate.traceExit(entryMessage)
// maybe this also?
def traceExit(message: Message): Unit = delegate.traceExit(message)
def traceExit[R](entryMessage: EntryMessage, result: R): R =
delegate.traceExit(entryMessage, result)
def traceExit[R](message: Message, result: R): R =
delegate.traceExit(message, result)
}
{code}
> Logger.entry and Logger.exit should support Messages.
