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.
