Bruno Navert commented on LBCORE-57:
------------------------------------
Here's example code using this: first a static utility method to retrieve all
Appenders
public static Set<Appender> getAllAppenders()
{
ContextSelector selector =
StaticLoggerBinder.SINGLETON.getContextSelector();
LoggerContext loggerContext = selector.getLoggerContext();
Map<String, Appender> appenders = newHashMap();
// loop through all Loggers
for ( Logger logger : loggerContext.getLoggerList() )
{
// for each logger, loop through all its appenders
Iterator iter = logger.iteratorForAppenders();
while ( iter.hasNext() )
{
// appenders are uniquely identified by name, so store them in
the Map thus
// this will overwrite the same entry in the Map many times
(with the same reference)
Appender appender = ( Appender ) iter.next();
appenders.put( appender.getName(), appender );
}
}
return newHashSet( appenders.values() );
}
Then code which runs once to load all flushable appenders in a list:
for ( Appender appender : LogbackConfigurer.getAllAppenders() )
{
if ( appender instanceof FlushableAppender )
{
flushableAppenders.add( ( FlushableAppender ) appender );
}
else
{
log.debug( "appender {} is not Flushable, skipping", appender );
}
}
And when needed, flush:
for ( FlushableAppender appender : flushableAppenders )
{
log.debug( "flushing appender {}", appender );
appender.flush();
}
