DESCRIPTION

The Attean::ListIterator class represents a typed iterator. It conforms to the Attean::API::RepeatableIterator role.

The Attean::ListIterator constructor requires two named arguments:

values

An array reference containing the items to iterate over.

item_type

A string representing the type of the items that will be returned from the iterator.

METHODS

reset

Resets the iterator's internal state so that iteration begins again at the beginning of the values array.

next

Returns the iterator's next item, or undef upon reaching the end of iteration.
