NAME

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

CONTENTS

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.

<B>This package is INCOMPLETE!B>

    Class and IDs

o $rs = DBIx::SQLEngine::RecordSet::Set->new_class_ids( $class, @ids );
o $rs->init_class_ids( $class, @ids );
o ( $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.
o @data = $rs->raw();

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

o $rs = $rs->as_RecordArray;

INCOMPLETE

o $clone = $rs->as_IDArray;

INCOMPLETE

o $clone = $rs->as_IDString;

INCOMPLETE

# $rs = DBIx::SQLEngine::RecordSet::Set->new_class_ids( $class, @ids ); sub new_ids {
my $callee = shift;
my $package = ref $callee || $callee;



  my $self = [];
  bless $self, $package;
  $self->init_class_ids( @_ );
  return $self;
}



# $rs->init_ids( $class, @ids ); sub init_ids {
my $self = shift;
my $class = shift;



  @$self = map { $class->fetch_id( $_ ) } @_;
}



# @records = $rs->class_ids(); sub class_ids {
my $self = shift;
my $class = ref( $self->[0] );
return $class, map { $_->{id} } @$self; }
