NAME

MongoDBx::Class::Cursor - A MongoDBx::Class cursor/iterator object for query results

VERSION

version 1.030002

EXTENDS

MongoDB::Cursor

SYNOPSIS

        my $cursor = $coll->find({ author => 'Conan Doyle' });

        print "Novels by Arthur Conan Doyle:\n";

        foreach ($cursor->sort({ year => 1 })->all) {
                print $_->title, '( ', $_->year, ")\n";
        }

DESCRIPTION

MongoDBx::Class::Cursor extends MongoDB::Cursor. At its basis, it adds automatic document expansion when traversing cursor results.

ATTRIBUTES

No special attributes are added.

OBJECT METHODS

Aside from methods provided by MonogDB::Cursor, the following method modifications are performed:

next( [ $do_not_expand ] )

Returns the next document in the cursor, if any. Automatically expands that document to the appropriate class (if '_class' attribute exists, otherwise document is returned as is). If $do_not_expand is true, the document will not be expanded and simply returned as is (i.e. as a hash-ref).

sort( $rules )

Adds a sort to the cursor and returns the cursor itself for chaining. $rules can either be an unordered hash-ref, an ordered Tie::IxHash object, or an ordered array reference such as this:

        $cursor->sort([ date => -1, time => -1, subject => 1 ])
