Class AvalonTee

java.lang.Object

org.apache.avalon.excalibur.logger.util.AvalonTee

All Implemented Interfaces:

org.apache.avalon.framework.activity.Disposable, org.apache.avalon.framework.activity.Startable, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.context.Contextualizable, org.apache.avalon.framework.logger.LogEnabled

Direct Known Subclasses:

LoggerManagerTee

public class AvalonTee
extends java.lang.Object
implements org.apache.avalon.framework.logger.LogEnabled, org.apache.avalon.framework.context.Contextualizable, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.activity.Startable, org.apache.avalon.framework.activity.Disposable

This class broadcasts Avalon lifestyle events to several destination objects, somewhat like Unix 'tee' command directing its input both to file and to its output. The current implementation is incomplete and handles only LogEnabled, Contextutalizable, Configurable and Disposable interfaces.

4.0
