*This* is critical. It is the difference between a logging system being
a simple string pipe and a /rich /log event data pump. The trappings as
to how exactly this occurs are less important as long as this capability
remains and is very efficient.
Jess,
You should have a look at logback which is designed around the
principle of specialized processing pipelines. There is logback-core, which is
logging agnostic, and there is logback-classic (equivalent of log4j) and there
is logback-access. The latter two are built on top of logback-core and are
mostly specialized processing chains for events of type ILoggingEvent
(logback-class) and of type AccessEvent (logback-access). Of course, this does
not preclude passing arbitrary objects to logback-classic.
