NAME

       Autodia::Handler::Torque.pm - AutoDia handler for Torque xml database schema

INTRODUCTION

       This provides Autodia with the ability to read Torque Database Schema files, allowing you to convert them
       via the Diagram Export methods to images (using GraphViz and VCG) or html/xml using custom templates or
       to Dia.

SYNOPSIS

       use Autodia::Handler::Torque;

       my $handler = Autodia::Handler::dia->New(\%Config);

       $handler->Parse(filename); # where filename includes full or relative path.

Description

       The Torque handler will parse the xml file using XML::Simple and populating the diagram object with
       class, superclass, and relationships representing tables and relationships.

       The Torque handler is registered in the Autodia.pm module, which contains a hash of language names and
       the name of their respective language.

       An example Torque database schema is shown here - its actually a rather nice format apart from the Java
       studlyCaps..

METHODS

   CONSTRUCTION METHOD
       use Autodia::Handler::Torque;

       my $handler = Autodia::Handler::Torque->New(\%Config); This creates a new handler using the Configuration
       hash to provide rules selected at the command line.

   ACCESS METHODS
       $handler->Parse(filename); # where filename includes full or relative path.

       This parses the named file and returns 1 if successful or 0 if the file could not be opened.
