All Implemented Interfaces:

java.io.Serializable
```
public final class LogLevel
extends org.apache.log4j.Level
```
Convenience class to provide SPL log levels through the org.apache.log4j facility.
The SPL log levels in descending order are:
- ERROR (highest value)
- WARN
- INFO (lowest value)
When a message is logged to the SPL log facility its org.apache.log4j.Level is mapped to the SPL log level as follows:
