Graph::Easy::Edge::Cell - A path-element in an edge
use Graph::Easy::Path; use Graph::Easy::Edge; my $ssl = Graph::Easy::Edge->new( label => 'encrypted connection', style => '-->', color => 'red', ); my $path = Graph::Easy::Path->new( type => EDGE_SHORT_E, ); $ssl->add_cell ($path); my $src = Graph::Easy::Node->new( name => 'source', ); my $dst = Graph::Easy::Node->new( name => 'destination', ); $graph = Graph::Easy->new(); $graph->add_edge($src, $dst, $ssl); print $graph->as_ascii();
A Graph::Easy::Path represents an edge between two (or more) nodes in a simple graph.
Graph::Easy::Path
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 associated with it.
$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);
Returns 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.
None by default. Can export the following on request:
EDGE_SHORT_E EDGE_SHORT_W EDGE_SHORT_N EDGE_SHORT_S EDGE_START_E EDGE_START_W EDGE_START_N EDGE_START_S EDGE_END_E EDGE_END_W EDGE_END_N EDGE_END_S EDGE_HOR EDGE_VER EDGE_CROSS EDGE_N_E EDGE_N_W EDGE_S_E EDGE_S_W EDGE_S_E_W EDGE_N_E_W EDGE_E_N_S EDGE_W_N_S EDGE_LABEL_CELL
Different ASCII styles:
,-----, +-----+ | Foo | --, vs. | Foo | --+ |_____| | +-----+ | | |
