ILogger (RoboLibJ - Javadocs)

java.lang.Object
- io.github.robolib.util.log.ILogger

Direct Known Subclasses:

Logger
```
public abstract class ILogger
extends java.lang.Object
```
A Logging class.
Each Class that wishes to log must call the Logger.get method with itself as the only argument, or with an optional string value. This will return a new Logger object.

To log something, the Calling class must call the desired level method info, debug, warn, error, fatal with the message to be logged. If the calling the err or fatal classes, a Throwable object must be passed as a second argument. Calling the error method will only print the message and error stack trace. However, calling the fatal method will print the stack trace, and kill the program.
