Interface Logger

All Known Implementing Classes:

LoggerFactory.DummyLogger, LoggerFactory.JavaUtilLogger, LoggerFactory.Slf4jLogger

public interface Logger

A lightweight wrapper around a logging API, if available.

We only support methods with Java varargs and expect, that logging calls are not time critical.

All log messages support SLF4j-style placeholders for arguments. (See also: http://www.slf4j.org/manual.html) You can use a {} (opening curly brace immediatly followed by a closing one) in the message which gets replaced by the next argument. To much placeholders will be left as is. Arguments not belonging to a placeholder are ignored. If the last argument is a Throwable, it will be not treated as argument for placeholders but as cause of the log message (and will be logged specially).
