How can my logging system add support for the Marker interface?
Markers constitute a revolutionary concept which is supported by logback but not other existing logging systems. Consequently, SLF4J conforming logging systems are allowed to ignore marker data passed by the user. However, even though marker data may be ignored, the user must still be allowed to specify marker data. Otherwise, users would not be able to switch between logging systems that support markers and those that do not. The MarkerIgnoringBase class can serve as a base for adapters or native implementations of logging systems lacking marker support. In MarkerIgnoringBase, methods taking marker data simply invoke the corresponding method without the Marker argument, discarding any Marker data passed as argument. Your SLF4J adapters can extend MarkerIgnoringBase to quickly implement the methods in org.slf4j.Logger which take a Marker as the first argument.
