NAME

Log::Log4perl::Level - Predefined log levels

SYNOPSIS


  use Log::Log4perl::Level;

  print $ERROR, "\n";





  # -- or --





  use Log::Log4perl qw(:levels);

  print $ERROR, "\n";

DESCRIPTION

"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

    $TRACE

    $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.
