Autodia::Handler::Perl.pm - AutoDia handler for perl
HandlerPerl parses files into a Diagram Object, which all handlers use. The role of the handler is to parse through the file extracting information such as Class names, attributes, methods and properties.
HandlerPerl parses files using simple perl rules. A possible alternative would be to write HandlerCPerl to handle C style perl or HandleHairyPerl to handle hairy perl.
HandlerPerl is registered in the Autodia.pm module, which contains a hash of language names and the name of their respective language - in this case:
%language_handlers = { .. , perl => "perlHandler", .. };
use Autodia::Handler::Perl;
my $handler = Autodia::Handler::Perl->New(\%Config);
This creates a new handler using the Configuration hash to provide rules selected at the command line.
$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.
$handler->output(); # any arguments are ignored.
This outputs the Dia XML file according to the rules in the %Config hash passed at initialisation of the object.
