NAME

DBIx::SQLEngine::RecordSet::PKeySet - A RecordSet which holds primary keys

SYNOPSIS

use DBIx::SQLEngine::RecordSet;

$rs = DBIx::SQLEngine::RecordSet->class( 'PKeySet' )->new(@records);

DESCRIPTION

Provides additional methods for a RecordSet to store primary keys instead of references to records.

This package is INCOMPLETE!

Class and IDs

• $rs = DBIx::SQLEngine::RecordSet::Set->new_class_ids( $class, @ids );

• $rs->init_class_ids( $class, @ids );

• ( $class, @ids ) = $rs->class_ids();

Conversions

Each of the below returns a RecordSet blessed into a particular subclass. Returns the original object if it is already of that subclass, or returns a cloned and converted copy.

• @data = $rs->raw();

  Returns the contents of the RecordSet as stored internally within the object. Results are dependent on which subclass is in use.

• $rs = $rs->as_RecordArray;

  INCOMPLETE

• $clone = $rs->as_IDArray;

  INCOMPLETE

• $clone = $rs->as_IDString;
