LoggerRepository ("The Adobe AEM Quickstart and Web Application.")

```
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 Detail
  - addHierarchyEventListener
```
void addHierarchyEventListener(HierarchyEventListener listener)
```
    Add a HierarchyEventListener event to the repository.
  - isDisabled
```
boolean isDisabled(int level)
```
    Returns whether this repository is disabled for a given level. The answer depends on the repository threshold and the level parameter. See also setThreshold(org.apache.log4j.Level) method.
  - setThreshold
```
void setThreshold(Level level)
```
    Set the repository-wide threshold. All logging requests below the threshold are immediately dropped. By default, the threshold is set to Level.ALL which has the lowest possible rank.
  - setThreshold
```
void setThreshold(java.lang.String val)
```
    Another form of setThreshold(Level) accepting a string parameter instead of a Level.
  - emitNoAppenderWarning
```
void emitNoAppenderWarning(Category cat)
```
  - getThreshold
```
Level getThreshold()
```
    Get the repository-wide threshold. See setThreshold(Level) for an explanation.
  - getLogger
```
Logger getLogger(java.lang.String name)
```
  - getLogger
```
Logger getLogger(java.lang.String name,
                 LoggerFactory factory)
```
  - getRootLogger
```
Logger getRootLogger()
```
  - exists
```
Logger exists(java.lang.String name)
```
  - shutdown
```
void shutdown()
```
  - getCurrentLoggers
```
java.util.Enumeration getCurrentLoggers()
```
  - getCurrentCategories
```
java.util.Enumeration getCurrentCategories()
```
    Deprecated. Please use getCurrentLoggers() instead.
  - fireAddAppenderEvent
```
void fireAddAppenderEvent(Category logger,
                          Appender appender)
```
  - resetConfiguration
```
void resetConfiguration()
```
