Class Logger

java.lang.Object

uk.co.caprica.vlcj.logger.Logger

public final class Logger
extends Object

A very simple lightweight log system.

The log level can be changed by invoking setLevel(Level).

The log level can be configured at run-time by specifying a system property on the command-line, for example:

   -Dvlcj.log=INFO
 

The log levels are defined in Logger.Level.
