Class SystemLogger

java.lang.Object

org.nineml.logging.Logger

org.nineml.logging.SystemLogger

public class SystemLogger
extends Logger

The system logger routes messages to another logging framework.

This class supports either configuration with org.slf4j.Logger or configuration directly with a java.util.logging.Logger.

This logger makes it easy to configure logging through a standard logging framework, as might be present on a Java application server. By default the logger uses the org.slf4j.LoggerFactory to create a logger. This logger can be supported at runtime by a wide variety of concrete backend classes. For details on how SLF4J finds a logging backend, see their documentation.

Alternatively, if you instantiate the SystemLogger with a java.util.logging.Logger directly, it will use that.
