Log::Log4perl::Level - Predefined log levels
use Log::Log4perl::Level; print $ERROR, "\n";
# -- or --
use Log::Log4perl qw(:levels); print $ERROR, "\n";
Log::Log4perl::Level
simply exports a predefined set of Log4perl log
levels into the caller's name space. It is used internally by
Log::Log4perl
. The following scalars are defined:
$OFF $FATAL $ERROR $WARN $INFO $DEBUG $ALL
Log::Log4perl
also exports these constants into the caller's namespace
if you pull it in providing the :levels
tag:
use Log::Log4perl qw(:levels);
This is the preferred way, there's usually no need to call
Log::Log4perl::Level
explicitely.
The numerical values assigned to these constants are purely virtual, only used by Log::Log4perl internally and can change at any time, so please don't make any assumptions.
If the caller wants to import these constants into a different namespace,
it can be provided with the use
command:
use Log::Log4perl::Level qw(MyNameSpace);
After this $MyNameSpace::ERROR
, $MyNameSpace::INFO
etc.
will be defined accordingly.
