Class FallbackLogger

java.lang.Object
de.iip_ecosphere.platform.configuration.FallbackLogger
All Implemented Interfaces:
org.slf4j.Logger
public class FallbackLogger extends Object implements org.slf4j.Logger
This is a poor man's fallback logger. Why not just a default implementation of SL4J. Because the logging implementation shall only be added during integration (architectural constraint C10), we may end up running the platform instantiator without any logging (as production code and we are not permitted to add a logging implementation). If there is a logging implementation at runtime, fine. If there is none, EASy will not complain about any error, not so good. This is the case for this poor man's logger, which is instantiated and used in the platform instantiator/lifecycle descriptor if there is no logging implementation (and the default one would disable all logging). While it delegates all logging to some rather simple (formatting) function, it completely ignores markers and cause throwables. If somebody needs this, please add. In it's current version, this logger is not intended for reuse, but who knows the future. Public for testing.
