NAME

Data::Hive::Store::Hash - store a hive in a flat hashref

VERSION

version 1.014

DESCRIPTION

This is a simple store, primarily for testing, that will store hives in a flat hashref. Paths are packed into strings and used as keys. The structure does not recurse -- for that, see Data::Hive::Store::Hash::Nested.

So, we could do this:

my $href = {};

my $hive = Data::Hive->NEW({
  store_class => 'Hash',
  store_args  => [ $href ],
});

$hive->foo->SET(1);
$hive->foo->bar->baz->SET(2);

We would end up with $href containing something like:

{
  foo => 1,
  'foo.bar.baz' => 2
}

PERL VERSION SUPPORT

This module has a long-term perl support period. That means it will not require a version of perl released fewer than five years ago.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.

METHODS

new

my $store = Data::Hive::Store::Hash->new(\%hash, \%arg);

The only argument expected for new is a hashref, which is the hashref in which hive entries are stored.

If no hashref is provided, a new, empty hashref will be used.

The extra arguments may include:

path_packer

A Data::Hive::PathPacker-like object used to convert between paths (arrayrefs) and hash keys.

hash_store

This method returns the hashref in which things are being used. You should not alter its contents!
