SYNOPSIS

9               use Graph::Easy;
10
11               my $ssl = Graph::Easy::Edge->new(
12                       label => 'encrypted connection',
13                       style => 'solid',
14                       color => 'red',
15               );
16               my $src = Graph::Easy::Node->new( 'source' );
17               my $dst = Graph::Easy::Node->new( 'destination' );
18
19               $graph = Graph::Easy->new();
20
21               $graph->add_edge($src, $dst, $ssl);

DESCRIPTION

26       A "Graph::Easy::Edge::Cell" represents an edge between two (or more)
27       nodes in a simple graph.
28
29       Each edge has a direction (from source to destination, or back and
30       forth), plus a style (line width and style), colors etc. It can also
31       have a name, e.g. a text label associated with it.
32
33       There should be no need to use this package directly.
34

METHODS

36   error()
37               $last_error = $edge->error();
38
39               $cvt->error($error);                    # set new messages
40               $cvt->error('');                        # clear error
41
42       Returns the last error message, or '' for no error.
43
44   as_ascii()
45               my $ascii = $path->as_ascii();
46
47       Returns the path-cell as a little ascii representation.
48
49   as_html()
50               my $html = $path->as_html($tag,$id);
51
52       eturns the path-cell as HTML code.
53
54   label()
55               my $label = $path->label();
56
57       Returns the name (also known as 'label') of the path-cell.
58
59   style()
60               my $style = $edge->style();
61
62       Returns the style of the edge.
