Class CachingDecorator

java.lang.Object
  org.apache.avalon.excalibur.logger.decorator.LoggerManagerDecorator
      org.apache.avalon.excalibur.logger.decorator.CachingDecorator

All Implemented Interfaces:

Configurable, Contextualizable, Disposable, LogEnabled, LoggerManager, Startable

public class CachingDecorator

extends LoggerManagerDecorator

This class implements LoggerManager interface by passing all the job to a wrapped LoggerManager, but the returened Loggers are cached. All operations of this class are synchronized via a single lock. As the LoggerManager is not expected to be a performance bottleneck probably this design will be good enough.
