Data-Classifier version 0.01
============================

This module provides tools to classify sets of data contained in hashes
against a predefined class hierarchy. Testing against a class is per-
formed using regular expressions stored in the class hierarchy. It is
also possible to modify the behavior of the system by subclassing and
overloading a few methods.

Note that this module may not be particularly usefull on its own. It is
designed to be used as a base class for implementing other systems,
such as Config::BuildHelper.

EXAMPLE

use strict;
use warnings;

use Data::Classifier;

my $yaml = <<EOY;
---
name: Root
children:
    - name: BMW
      children:
          - name: Diesel
            match:
                  model: "d\$"
          - name: Sports
            match:
                  model: "i\$"
                  seats: 2
          - name: Really Expensive
            match:
                  model: "^M"
EOY

my $classifier = Data::Classifier->new(yaml => $yaml);
my $attributes1 = { model => '325i', seats => 4 };
my $class1 = $classifier->process($attributes1);
my $attributes2 = { model => '535d', seats => 4 };
my $class2 = $classifier->process($attributes2);
my $attributes3 = { model => 'M3', seats => 2 };
my $class3 = $classifier->process($attributes3);
print "$attributes2->{model}: ", $class2->fqn, "\n";
print "$attributes3->{model}: ", $class3->fqn, "\n";
#no real sports car has 4 seats
print "$attributes1->{model}: ", $class1->fqn, "\n";

__END__

Which will output:

535d: Root::BMW::Diesel
M3: Root::BMW::Really Expensive
325i:
