Fey::Object::Iterator::FromSelect::Caching - A caching subclass of Fey::Object::Iterator::FromSelect

VERSION

version 0.47

SYNOPSIS

  use Fey::Object::Iterator::FromSelect::Caching;

  my $iter = Fey::Object::Iterator::FromSelect::Caching->new(
      classes     => 'MyApp::User',
      select      => $select,
      dbh         => $dbh,
      bind_params => \@bind,
  );

  print $iter->index();    # 0

  while ( my $user = $iter->next() ) {
      print $iter->index();    # 1, 2, 3, ...
      print $user->username();
  }

  # will return cached objects now
  $iter->reset();

DESCRIPTION

This class implements a caching subclass of Fey::Object::Iterator::FromSelect. This means that it caches objects it creates internally. When $iterator->reset() is called it will re-use those objects before fetching more data from the DBMS.

METHODS

This class provides the following methods:

$iterator->reset()

Resets the iterator so that the next call to $iterator->next() returns the first objects. Internally, this does not reset the DBI statement handle, it simply makes the iterator use cached objects.

$iterator->clone()

Clones the iterator while sharing its cached data with the original object. This is really intended for internal use, so use at your own risk.

ROLES

This class does the Fey::ORM::Role::Iterator role.
