Field Detail

m_fallback

org.apache.avalon.framework.logger.Logger m_fallback

m_preferred

org.apache.avalon.framework.logger.Logger m_preferred

m_recursionOnPreferred

LoggerSwitch.BooleanThreadLocal m_recursionOnPreferred

m_recursionOnFallback

LoggerSwitch.BooleanThreadLocal m_recursionOnFallback

Constructor Detail

LoggerSwitch.SwitchingLogger

LoggerSwitch.SwitchingLogger(org.apache.avalon.framework.logger.Logger fallback,
                            org.apache.avalon.framework.logger.Logger preferred)

Method Detail

setFallback

void setFallback(org.apache.avalon.framework.logger.Logger fallback)

setPreferred

void setPreferred(org.apache.avalon.framework.logger.Logger preferred)

getLogger

private org.apache.avalon.framework.logger.Logger getLogger()

Retrieve m_preferred or if that is null m_fallback. Safeguard against recursion. That is possible if try to log something via a Logger that is failing and trying to log its own error via itself.

getLoggerLight

private org.apache.avalon.framework.logger.Logger getLoggerLight()

releaseLogger

private void releaseLogger()

debug

public void debug(java.lang.String message)

Specified by:

debug in interface org.apache.avalon.framework.logger.Logger

debug

public void debug(java.lang.String message,
         java.lang.Throwable throwable)

Specified by:

debug in interface org.apache.avalon.framework.logger.Logger

isDebugEnabled

public boolean isDebugEnabled()

This and similar method may probably be optimized in the future by caching the boolean in our instance variables. Each time setPreferred() or setFallback() is called they will be cached. Maybe in the future. :-)

Specified by:

isDebugEnabled in interface org.apache.avalon.framework.logger.Logger
