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 %options hash supports the following keys:

vertices

Array of vertices.
