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 messags
	       $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.
