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 performed 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:
