LogManager
class to retreive Logger
instances or to operate on the current LoggerRepository

class is loaded
into memory the default initalzation procedure is inititated. The

set to null but is assumed to be harmless since the
all classes are in the process of being unloaded.

public static void setRepositorySelector(RepositorySelector selector, Object guard) throws IllegalArgumentException
LoggerFactory
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 a IllegalArgumentException
, unless the previously set
guard
is passed as the second parameter.
This allows a high-level component to set the RepositorySelector
used by the LogManager
.
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.
