Package com.pixelmed.slf4j

Class Logger

  • public class Logger
extends java.lang.Object

    This class implements a thin wrapper around a subset of methods of the Logger class from the SLF4J facade, in order to allow those methods commonly used by the toolkit to be usable without invoking a runtime dependency on the SLF4J jar files.

    For how to configure the logger properties, see the package description.
