CatalystX::CRUD::Iterator - generic iterator wrapper for CXCM iterator results

NAME

CatalystX::CRUD::Iterator - generic iterator wrapper for CXCM iterator() results

SYNOPSIS

 package MyApp::Model::MyModel;
 use CatalystX::CRUD::Iterator;
 use MyModel;
 __PACKAGE__->config->{object_class} = 'MyModel::Object';
 
 sub iterator {
     my ($self, $query) = @_;
     
     my $iterator = MyModel->search_for_something;
     
     # $iterator must have a next() method
     
     return CatalystX::CRUD::Iterator->new(
                                        $iterator,
                                        $self->object_class
                                        );
 }

DESCRIPTION

CatalystX::CRUD::Iterator is a general iterator class that wraps a real iterator and blesses return results into a specified class. CatalystX::CRUD::Iterator is a glue that provides for a similar level of abstraction across all kinds of CXCM classes.

METHODS

new( iterator, class_name )

Returns a CatalystX::CRUD::Iterator instance.

iterator must have a next() method and (optionally) a finish() method.

See next().

next

Calls the next() method on the internal iterator object, stashing the result in an object returned by class_name->new under the method_name accessor.

finish

If the internal iterator object has a finish() method, this will call and return it. Otherwise returns true (1).
