  +--com.cafesoft.core.log.StdoutLogger

All Implemented Interfaces:

Logger

public class StdoutLogger

extends Object

implements Logger

Logs message to the System.out OutputStream. By default, the "MessageLevelMessageFilter" is installed and used with all message levels enabled.

Since:

4/10/02

Field Summary

static StdoutLogger	DEFAULT_STDOUT_LOGGER Most objects create a StdoutLogger object as there default logger as to avoid NullPointerExceptions when attempting to log information However, the end result is that each object create's it's own logger that is basically the same accross the board.
protected MessageFilter	messageFilter The MessageFilter used to discriminate messages to be logged.
protected Properties	properties Configuration Properties.
protected boolean	verbose Boolean flag that indicates if the logger is printing verbose information such as the class name

Field Detail

DEFAULT_STDOUT_LOGGER

public static final StdoutLogger DEFAULT_STDOUT_LOGGER

Most objects create a StdoutLogger object as there default logger as to avoid NullPointerExceptions when attempting to log information However, the end result is that each object create's it's own logger that is basically the same accross the board. This logger is the single instance that all objects should be initialized with. However, this is not a Singleton design as it is completely possible to have and need several unique instances of a StdoutLogger.
