InternalLoggerFactory (Netty API Reference (5.0.0.Alpha4))

java.lang.Object
- io.netty5.util.internal.logging.InternalLoggerFactory

Direct Known Subclasses:

CommonsLoggerFactory, JdkLoggerFactory, Log4J2LoggerFactory, Slf4JLoggerFactory
```
public abstract class InternalLoggerFactory
extends Object
```
Creates InternalLoggers. This factory allows you to choose what logging framework Netty should use. The default factory is Slf4JLoggerFactory. If SLF4J is not available, Log4J2LoggerFactory is used. If Log4J is not available, JdkLoggerFactory is used. You can change it to your preferred logging framework before other Netty classes are loaded via setDefaultFactory(InternalLoggerFactory). If you want to change the logger factory, setDefaultFactory(InternalLoggerFactory) must be invoked before any other Netty classes are loaded. Note that setDefaultFactory(InternalLoggerFactory)} can not be invoked more than once.
