Autodia::Handler::Torque (3pm)

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 \s-1VCG\s0) or html/xml using custom templates or to Dia.

use Autodia::Handler::Torque;

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

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

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..
