Package com.objectwave.logging Description

Introduction
The logging package was created to maintain a buffer between ObjectWave code and third party dependencies. By using the logging package, code created is not tied to any one logging implementation. Implementations can be "plugged-in". Examples of different plugins might be Apache's Log4J logging system, or perhaps a Unix like syslog plugin.
Custom logging implementations are accessed via the adapter pattern which requires custom implementations to provide a LogIF adapter class. This adapter is then set as the LoggingEngine in the MessageLog class via the setLoggingEngine(LogIf) method.

MessageLog
The message log class is the main entry point into the logging package for client code. This should be the only class required to perform any of your logging needs. See the API for details.


Current LogIF implementations
com.objectwave.logging.ConsoleImpl - This implementation simply logs to stdout.
com.objectwave.logging.log4j.Log4jImpl - This is the adapter which connects the logging system to the Apache Log4j logging system.
