NAME

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

VERSION

version 1.015

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

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

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!
