NAME

Graph::Easy::Node::Cell - An empty filler cell

SYNOPSIS

        use Graph::Easy::Path;
        use Graph::Easy::Edge;

        my $ssl = Graph::Easy::Edge->new(
                label => 'encrypted connection',
                style => '-->',
                color => 'red',
        );
        my $path = Graph::Easy::Path->new(
                type => EDGE_SHORT_E,
        );
        $ssl->add_cell ($path);

        my $src = Graph::Easy::Node->new(
                name => 'source',
        );

        my $dst = Graph::Easy::Node->new(
                name => 'destination',
        );

        $graph = Graph::Easy->new();

        $graph->add_edge($src, $dst, $ssl);

        print $graph->as_ascii();

DESCRIPTION

A Graph::Easy::Group::Cell represents an edge between two (or more) nodes in a simple graph. It is also used to reserve a cell in the grid for nodes that occupy more than one cell.

Each edge has a direction (from source to destination, or back and forth), plus a style (line width and style), colors etc. It can also have a name, e.g. a text associated with it.

METHODS

error()

        $last_error = $edge->error();

        $cvt->error($error);                    # set new messags
        $cvt->error('');                        # clear error

Returns the last error message, or '' for no error.
