VERSION

version 1.003

SYNOPSIS

package Metabase::Archive::Foo;
use Metabase::Fact;
use Moose;
with 'Metabase::Archive';

# define Moose attributes

sub store {
  my ( $self, $fact_struct ) = @_;
  # store a fact
}

sub extract {
  my ( $self, $guid ) = @_;
  # retrieve a fact
  return $fact;
}

sub delete {
  my ( $self, $guid ) = @_;
  # delete a fact;
  return;
}

sub iterator {
  my ( $self ) = @_;
  # get iterator as Data::Stream::Bulk object
  return $iterator;
}

sub initialize {
  my ($self, @fact_classes) = @_;
  # prepare backend to store data (e.g. create database, etc.)
  return;
}

DESCRIPTION

This describes the interface for storing and retrieving facts. Implementations must provide the store, extract, delete, iterator and initialize methods. initialize must be idempotent. iterator must return a Data::Stream::Bulk object.
