org.ops4j.pax.logging.logback.internal.bridges.PaxAppenderDelegate

All Implemented Interfaces:

ch.qos.logback.core.Appender<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.ContextAware, ch.qos.logback.core.spi.FilterAttachable<ch.qos.logback.classic.spi.ILoggingEvent>, ch.qos.logback.core.spi.LifeCycle

public class PaxAppenderDelegate
extends ch.qos.logback.core.UnsynchronizedAppenderBase<ch.qos.logback.classic.spi.ILoggingEvent>

This is a Logback appender that forwards log messages to any services registered with OSGi with the interface org.ops4j.pax.logging.spi.PaxAppender. That list of appender services is possibly filtered by the paxname setting.

For example, you can use it like this in your logback.xml file:

   <appender name="OSGI" class="org.ops4j.pax.logging.logback.appender.PaxAppenderDelegate">
       <paxname>*</paxname>
   </appender>
 

The paxname argument is a filter for the bundle property "org.ops4j.pax.logging.appender.name". In this example, the "*" means to accept all delegatees.

This class is inspired by PaxLoggingConfigurator.parseAppender(), PaxAppenderProxy and AppenderBridgeImpl in the log4j implementation.
