NAME

Fey::Object::Iterator::FromArray - An iterator which iterates over an array of objects

VERSION

version 0.47

SYNOPSIS

use Fey::Object::Iterator::FromArray;

my $iter = Fey::Object::Iterator::FromArray->new(
    classes => 'MyApp::User',
    objects => \@users,
);

my $iter2 = Fey::Object::Iterator::FromArray->new(
    classes => [ 'MyApp::User', 'MyApp::Group' ],
    objects => [ [ $user1, $group1 ], [ $user2, $group1 ] ],
);

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 provides an object which does the Fey::ORM::Role::Iterator role, but gets its data from an array reference. This lets you provide a single API that accepts data from Fey::ORM-created iterators, or existing data sets.

METHODS

This class provides the following methods:

$iterator->new()

The constructor requires two parameters, classes and objects. The classes parameter can be a single class name, or an array reference of names.

The objects parameter should be an array reference. That reference can contain a list of objects, or an a list of array references, each of which contains objects.

In either case, the objects must be subclasses of Fey::Object::Table.

$iterator->reset()

Resets the iterator so that the next call to $iterator->next() returns the first object(s).

ROLES

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