Graph::Easy::Edge::Cell - A cell in an edge in Graph::Easy
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();
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.
$last_error = $edge->error(); $cvt->error($error); # set new messags $cvt->error(''); # clear error
Returns the last error message, or '' for no error.
my $ascii = $path->as_ascii();
Returns the path-cell as a little ascii representation.
my $html = $path->as_html($tag,$id);
eturns the path-cell as HTML code.
my $label = $path->label();
Returns the name (also known as 'label') of the path-cell.
my $style = $edge->style();
Returns the style of the edge.
