- All Known Implementing Classes:
Hierarchy,NOPLoggerRepository
public interface LoggerRepository
A
LoggerRepository is used to create and retrieve Loggers.
The relation between loggers in a repository depends on the repository but typically loggers are arranged in a named hierarchy.
In addition to the creational methods, a LoggerRepository can be queried for existing loggers, can act
as a point of registry for events related to loggers.

Method Details
-
addHierarchyEventListener
Add aHierarchyEventListenerevent to the repository.- Parameters:
listener- The listener
-
isDisabled
boolean isDisabled(int level) Returns whether this repository is disabled for a given level. The answer depends on the repository threshold and thelevelparameter. See alsosetThreshold(org.apache.log4j.Level)method.- Parameters:
level- The level- Returns:
- whether this repository is disabled.
-
setThreshold

level- The level
-
setThreshold
Another form ofsetThreshold(Level)accepting a string parameter instead of aLevel.- Parameters:
val- The threshold value
