- Enclosing interface:
- System.Logger
System loggers levels.
A level has a name and severity.
Level values are
ALL, TRACE, DEBUG,
INFO, WARNING, ERROR, OFF,
by order of increasing severity.
ALL and OFF
are simple markers with severities mapped respectively to
Integer.MIN_VALUE and
Integer.MAX_VALUE.
Severity values and Mapping to java.util.logging.Level.
System logger levels are mapped to
java.util.logging levels
of corresponding severity.
The mapping is as follows:
| System.Logger Levels | java.util.logging Levels |
|---|---|
ALL |
ALL |
TRACE |
FINER |
DEBUG |
FINE |
INFO |
INFO |
WARNING |
