NAME

       Log::Log4perl::Filter::LevelRange - Filter for a range of log levels

SYNOPSIS

	   log4perl.filter.Match1		= Log::Log4perl::Filter::LevelRange
	   log4perl.filter.Match1.LevelMin	= INFO
	   log4perl.filter.Match1.LevelMax	= ERROR
	   log4perl.filter.Match1.AcceptOnMatch = true

DESCRIPTION

       This Log4perl custom filter checks if the current message has a priority matching a predefined range.  The "LevelMin" and "LevelMax"
       parameters define the levels (choose from "DEBUG", "INFO", "WARN", "ERROR", "FATAL") marking the window of allowed messages priorities.
       The additional parameter "AcceptOnMatch" defines if the filter is supposed to pass or block the message ("true" or "false").

NAME

       Log::Log4perl::Level - Predefined log levels

SYNOPSIS

	 use Log::Log4perl::Level;
	 print $ERROR, "
";

	 # -- or --

	 use Log::Log4perl qw(:levels);
	 print $ERROR, "
";

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.

   Numeric levels and Strings
       Level variables like $DEBUG or $WARN have numeric values that are internal to Log4perl. Transform them to strings that can be used in a
       Log4perl configuration file, use the c<to_level()> function provided by Log::Log4perl::Level:

	   use Log::Log4perl qw(:easy);
	   use Log::Log4perl::Level;

	       # prints "DEBUG"
	   print Log::Log4perl::Level::to_level( $DEBUG ), "
";

       To perform the reverse transformation, which takes a string like "DEBUG" and converts it into a constant like $DEBUG, use the to_priority()
       function:

	   use Log::Log4perl qw(:easy);
	   use Log::Log4perl::Level;

	   my $numval = Log::Log4perl::Level::to_priority( "DEBUG" );

       after which $numval could be used where a numerical value is required:

	   Log::Log4perl->easy_init( $numval );
