VERSION

version 1.001

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.
