NAME
Graph::Feather - Like Graph::Directed basics, but with SQLite backend
SYNOPSIS
use Graph::Feather;
my $g = Graph::Feather->new;
$g->add_edge(...);
$g->has_edge(...)
$g->delete_edge(...);
...DESCRIPTION
Light-weight drop-in replacement for Graph::Directed using SQLite to store directed graph data. Only basic graph manipulation functions are supported. Some applications may find this module faster and/or use less memory than Graph::Directed, particularily when using edge or vertex attributes.
The test suite ensures the behavior of each method is equivalent to those in Graph::Directed when called with legal arguments.
CONSTRUCTOR
- new(%options)
-
The
%optionshash supports the following keys:- vertices
-
Array of vertices.
- edges
-
Array of edges.

EXTENSIONS
- feather_export_to($compatible_graph)
-
Adds vertices, edges, their attributes, and any graph attributes to the target graph, overwriting any existing attributes.
- feather_import_from($compatible_graph)
-
Adds vertices, edges, their attributes, and any graph attributes from the other graph, overwriting any existing attributes.
- feather_delete_edges(@edges)
-
In the original Graph module,
delete_edgestakes a flat list of vertices instead of a list of vertex pairs. This function takes a list of vertex pairs instead.
