public class Logger

extends java.lang.Object

implements Log

Logger singleton. This class will read the log class from the commerce properties. This class must implement the Log interface. If it is not found or If there is a problem creating the specified log class, it will use the std err log. For purely convenience reasons, this class has implemented the Log interface and delegates to the instantiated 'Log'. So instead of doing Logger.getInstance().getLog().log(), you can do Logger.getInstance().log(). NOTE: Both methods are valid and write to identical logs. Also since the singleton implements the Log interface, the constants are available off of Logger, e.g. Logger.LOG_DEBUG == Log.LOG_DEBUG.
