NAME

       Autodia::Diagram - Class to hold a collection of objects representing parts of a Dia
       Diagram.

SYNOPSIS

       use Autodia::Diagram;

       my $Diagram = Autodia::Diagram->new;

   Description
       Diagram is an object that contains a collection of diagram elements and the logic to
       generate the diagram layout as well as to output the diagram itself in Dia's XML format
       using template toolkit.

METHODS

   Class Methods
       new - constructor method
           creates and returns an unpopulated diagram object.

   Object methods
       To get a collection of a objects of a certain type you use the method of the same name. ie
       $Diagram->Classes() returns an array of 'class' objects.

       The methods available are Classes(), Components(), Superclasses(), Inheritances(),
       Relations(), and Dependancies(); These are all called in the template to get the
       collections of objects to loop through.

       To add an object to the diagram. You call the add_<object type> method, for example
       $Diagram->add_class($class_name), passing the name of the object in the case of Class,
       Superclass and Component but not Inheritance or Dependancy which have their names
       generated automagically.

       Objects are not removed, they can only be superceded by another object; Component can be
       superceded by Superclass which can superceded by Class. This is handled by the object
       itself rather than the diagram.

   Accessing and manipulating the Diagram
       Elements are added to the Diagram through the add_<elementname> method (ie add_classes()
       ).

       Collections of elements are retrieved through the <elementname> method (ie Classes() ).

       The diagram is laid out and output to a file using the export_xml() method.
