Handel::Iterator::DBIC - Iterator class used for collection looping DBIC resultsets

    my $resultset = $schema->resultset('Carts')->search;

    my $iterator = Handel::Iterator::DBIC->new({
        data         => $resultset,
        result_class => 'MyResult',
        storage      => $storage
    });

    while (my $result = $iterator->next) {
        print $result->method;
    };

Handel::Iterator::DBIC is a used to iterate through results stored in a resultset returned from DBIx::Class.

Arguments: \%options

Creates a new iterator object. The following options are available:

    my $resultset = $schema->resultset('Carts')->search;

    my $iterator = Handel::Iterator::DBIC->new({
        data         => $resultset,
        result_class => 'MyResult',
        storage      => $storage
    });

    my $result = $iterator->first;
    print ref $result; # MyResult

data

The data to be iterated through. This should be a DBIx::Class::ResultSet.

result_class

The name of the class that each result should be inflated into.

storage

The storage object that was used to create the results.

Returns all results from current iterator.

    foreach my $result ($iterator->all) {
        print $result->method;
    };

Returns the number of results in the current iterator.

    my $count = $iterator->count;

Arguments: $result [, $storage]

Returns a new result class object based on the specified result and storage objects. If no storage object is specified, the storage object passed to new will be used instead.

This method is used by methods like first and next to to create storage result objects. There is probably no good reason to use this method directly.

Returns the first result or undef if there are no results.

    my $first = $iterator->first;

Returns the last result or undef if there are no results.

    my $last = $iterator->last;

Returns the next result or undef if there are no results.

    while (my $result = $iterator->next) {
        print $result->method;
    };

Resets the current result position back to the first result.

    while (my $result = $iterator->next) {
        print $result->method;
    };

    $iterator->reset;

    while (my $result = $iterator->next) {
        print $result->method;
    };
