RE: cvs commit: jakarta-log4j/src/java/org/apache/log4j/spi Logge rRepositoryEventListener.java LoggerEventListener.java

[Nicko Cadell <ni...@Neoworks.com>]

Just a quick question about the LoggerRepositoryEventListener:

When will the LoggerRepositoryEventListener.startupEvent be fired?

If it is fired when the repository is created, then no listeners will 
have been registered. 

Is this really a ConfiguredEvent fired after the repository has been 
configured? If so who is responsible for triggering it? One of the 
Configurators or the repository itself?

Thanks,
Nicko
