getName in interface Logger

name of this logger instance

readResolve

protected Object readResolve()
                      throws ObjectStreamException

Replace this instance with a homonymous (same name) logger returned by LoggerFactory. Note that this method is only called during deserialization.

This approach will work well if the desired ILoggerFactory is the one references by LoggerFactory. However, if the user manages its logger hierarchy through a different (non-static) mechanism, e.g. dependency injection, then this approach would be mostly counterproductive.

Returns:

logger with same name as returned by LoggerFactory

Throws:

ObjectStreamException
