setRepositorySelector
public static void setRepositorySelector(RepositorySelector selector, Object guard) throws IllegalArgumentException SetsLoggerFactory
but only if the correct guard is passed as parameter.Initally the guard is null. If the guard is
null
, then invoking this method sets the logger factory and the guard. Following invocations will throw aIllegalArgumentException
, unless the previously setguard
is passed as the second parameter.This allows a high-level component to set the
RepositorySelector
used by theLogManager
.For example, when tomcat starts it will be able to install its own repository selector. However, if and when Tomcat is embedded within JBoss, then JBoss will install its own repository selector and Tomcat will use the repository selector set by its container, JBoss.
