NAME

Data::Hive::Store - a backend storage driver for Data::Hive

VERSION

version 1.013

DESCRIPTION

Data::Hive::Store is a generic interface to a backend store for Data::Hive.

METHODS

All methods are passed at least a 'path' (arrayref of namespace pieces). Store classes exist to operate on the entities found at named paths.

get

  print $store->get(\@path, \%opt);

Return the resource represented by the given path.

set

  $store->set(\@path, $value, \%opt);

Analogous to get.

name

  print $store->name(\@path, \%opt);

Return a store-specific name for the given path. This is primarily useful for stores that may be accessed independently of the hive.

exists

  if ($store->exists(\@path, \%opt)) { ... }

Returns true if the given path exists in the store.

delete

  $store->delete(\@path, \%opt);

Delete the given path from the store. Return the previous value, if any.

Stores can also implement delete_all to delete this path and all paths below it. If delete_all is not provided, the generic one-by-one delete in this class will be used.

keys

  my @keys = $store->keys(\@path, \%opt);

This returns a list of next-level path elements that lead toward existing values. For more information on the expected behavior, see the KEYS method in Data::Hive.
