Class Log

java.lang.Object

org.cache2k.impl.util.Log

Direct Known Subclasses:

Log.SuppressionCounter

public abstract class Log
extends Object

cache2k has only sparse logging. The direct use of java.util.logging was examined. However, a thread name is missing within the output and it is not properly recorded. To have the chance to redirect any logging to the framework of choice, the log output is channeled through this class.

To hook in another log framework provide another LogFactory implementation via the service loader.
