NAME

Catmandu::Store::Hash - An in-memory store

SYNOPSIS

   use Catmandu;

   my $store = Catmandu->store('Hash');

   my $obj1 = $store->bag->add({ name => 'Patrick' });

   printf "obj1 stored as %s\n" , $obj1->{_id};

   # Force an id in the store
   my $obj2 = $store->bag->add({ _id => 'test123' , name => 'Nicolas' });

   my $obj3 = $store->bag->get('test123');

   $store->bag->delete('test123');

   $store->bag->delete_all;

   # All bags are iterators
   $store->bag->each(sub { ... });
   $store->bag->take(10)->each(sub { ... });

DESCRIPTION

A Catmandu::Store::Hash is an in-memory Catmandu::Store backed by a hash for fast retrieval combined with a doubly linked list for fast traversal.

METHODS

new([init_data => [...] ])

Create a new Catmandu::Store::Hash. Optionally provide as init_data an array ref of data:

    my $store = Catmandu->store('Hash', init_data => [
           { _id => 1, data => foo } ,
           { _id => 2, data => bar }
    ]);

    # or in a catmandu.yml configuration file:

    ---
    store:
       hash:
         package: Hash
         options:
            init_data:
               - _id: 1
                 data: foo
               - _id: 2
                 data: bar
