Class DefaultLogger

    java.lang.Object
      com.puppycrawl.tools.checkstyle.api.AutomaticBean
          com.puppycrawl.tools.checkstyle.DefaultLogger

All Implemented Interfaces:
  AuditListener, Configurable, Contextualizable, EventListener

    public class DefaultLogger

extends AutomaticBean
implements AuditListener

Simple plain logger for text output. This is maybe not very suitable for a text output into a file since it does not need all 'audit finished' and so on stuff, but it looks good on stdout anyway. If there is really a problem this is what XMLLogger is for. It gives structure.
