Method Detail

log

protected final void log(String s)

Description copied from class: AbstractSimpleImpl

How to write one string. Only to be called by AbstractSimpleImpl.log(String, Level). Default this does nothing, you must override this, or AbstractSimpleImpl.log(String, Level).

Overrides:

log in class AbstractSimpleImpl

debug

public void debug(Object message)

Description copied from interface: Logger

Logs the message m with debug priority. Everything a non-developer never wants to see, but you do, to * keep track of what is happening. There can be a lot of them in the code, so it is important that you well protect them with `isDebugEnabled's, to minimize overhead.

Specified by:

debug in interface Logger

Overrides:

debug in class AbstractSimpleImpl

error

public void error(Object message)

Description copied from interface: Logger

Logs the message m with error priority. Something is definitely wrong. An inconsistency was detected. It might be unpredictable what will happen.

Specified by:

error in interface Logger

Overrides:

error in class AbstractSimpleImpl

fatal

public void fatal(Object message)

Description copied from interface: Logger

Logs the message m with fatal priority. The progam could not function any more. Normally, you would throw an exception, which then will be logged with fatal priority. I've made an arangement in `Logger' that logs uncatched exceptions with fatal priority, but nevertheless it's better to always catch all exceptions in a more regulated way.

Specified by:

fatal in interface Logger

Overrides:

fatal in class AbstractSimpleImpl

info

public void info(Object message)

Description copied from interface: Logger

Logs the message m with info priority. As `service', but focussed on things system administrators are usually most interested in, like authorisation issues. For example changes on the database could be logged, such that one can see in the logs what happened.

Specified by:

info in interface Logger

Overrides:

info in class AbstractSimpleImpl

service

public void service(Object message)

Description copied from interface: Logger

Logs the message m with service priority. An interested system administrator might want to see these things. For examples all queries to the database could be logged with `service' priority. Or if a image is calculated, that could be logged as a `service'. One would get a fairly good idea what MMBase is doing if `service' is switched on.

Specified by:

service in interface Logger

Overrides:

service in class AbstractSimpleImpl

trace

public void trace(Object message)

Description copied from interface: Logger

Logs the message m with trace priority. For detailled debugging.

Specified by:

trace in interface Logger

Overrides:

trace in class AbstractSimpleImpl

See Also:

Logger.debug(Object)

warn

public void warn(Object message)

Description copied from interface: Logger

Logs the message m with warn priority. Something strange happened, but it is not necessarily an error.

Specified by:

warn in interface Logger

Overrides:

warn in class AbstractSimpleImpl

                  Throwable t)
