NAME Map::Tube::Graph - Graph output for Map::Tube. SYNOPSIS use Map::Tube::Graph; my $obj = Map::Tube::GraphViz->new(%params); my $graph = $obj->graph; METHODS "new(%params)" Constructor. * "callback_edge" Edge callback. Default value is this: sub { my ($self, $node, $link) = @_; $self->{'graph'}->add_edge($node->id, $link); return; } * "callback_vertex" Vertex callback. Default value is this: sub { my ($self, $node) = @_; $self->{'graph'}->add_vertex($node->id); return; } * "graph" Graph object. Default value is Graph->new. * "tube" Map::Tube object. It is required. Default value is undef. "graph()" Get Graph object. Returns Graph object. ERRORS new(): Cannot load UNIVERSAL::DOES module. Parameter 'tube' is required. Parameter 'tube' must be 'Map::Tube' object. From Class::Utils::set_params(): Unknown parameter '%s'.
