NAME

       Graph::Easy::Edge::Cell - A cell in an edge in Graph::Easy

SYNOPSIS

               use Graph::Easy;

               my $ssl = Graph::Easy::Edge->new(
                       label => 'encrypted connection',
                       style => 'solid',
                       color => 'red',
               );
               my $src = Graph::Easy::Node->new( 'source' );
               my $dst = Graph::Easy::Node->new( 'destination' );

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

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

               print $graph->as_ascii();

DESCRIPTION

       A "Graph::Easy::Edge::Cell" represents an edge between two (or more) nodes in a simple
       graph.

       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 label associated
       with it.

       There should be no need to use this package directly.

METHODS

   error()
               $last_error = $edge->error();

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

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

   as_ascii()
               my $ascii = $path->as_ascii();

       Returns the path-cell as a little ascii representation.

   as_html()
               my $html = $path->as_html($tag,$id);

       eturns the path-cell as HTML code.

   label()
               my $label = $path->label();

       Returns the name (also known as 'label') of the path-cell.

   style()
               my $style = $edge->style();

       Returns the style of the edge.
