level
- The Level

- The threshold Level
true
if the evaluated level is above the required
threshold.
Note(s):
If either argument is null
then result is false
.
If the evaluated level is Level.OFF
then result is false
regardless of the threshold.
If the threshold is Level.ALL
and the evaluated level is
not Level.OFF
the result is true
.
Otherwise, the evaluated level Level.intValue()
must be
greater or equal to the threshold.

logger
- The Logger
instance - ignored if null
level
- The validate log Level
- ignored if null
true
if the level is enabled for the logger. The
mapping of the level to the logger is as follows:
Level.OFF
always returns false
Level.SEVERE
returns Logger.isErrorEnabled()
Level.WARNING
returns Logger.isWarnEnabled()
Level.INFO
and Level.ALL
returns Logger.isInfoEnabled()
Level.CONFIG
and Level.FINE
returns Logger.isDebugEnabled()
Logger.isTraceEnabled()
