=head1 NAME

Log::Fine::Levels::Java - Provides levels correlating to java.utils.logging

=head1 SYNOPSIS

Defines log level values and masks correlating to those provided by
java.utils.logging

    use Log::Fine;
    use Log::Fine::Levels::Java;

    # Grab a logging object
    my $log = Log::Fine->getLogger("foo1");

    # Note that FINER and SEVERE are provided by the
    # Log::Fine::Levels::Java object
    $log->log(FINER, "I'm not mad at you, I'm mad at the dirt");
    $log->log(SEVERE, "No more wire hangers ... EVER!");

=head1 DESCRIPTION

Log::Fine::Levels::Java provides logging and mask constants mimicking
those provided by the C framework as provided by
Java 1.5.0

use strict;
use warnings;

package Log::Fine::Levels::Java;

use AutoLoader;
use Carp;
use Exporter;
use POSIX qw( strftime );

use base qw/ Log::Fine::Levels Exporter /;

our $VERSION = $Log::Fine::Levels::VERSION;

# Necessary for AutoLoader
our $AUTOLOAD;

=head2 Log Levels

Log::Fine::Levels::Java bases its log levels on those provided by
C.  See
L
for further specifics.

=head2 Log Masks

Log masks can be exported for use in setting up individual handles
(see L).  The following masks are exported into the
caller namespace:
