NAME

       Attean::IteratorSequence - Iterator implementation backed by zero or more sub-iterators

VERSION

       This document describes Attean::IteratorSequence version 0.019

SYNOPSIS

         use v5.14;
         use Attean;
         my $iter = Attean::IteratorSequence->new(iterators => [$iter1, $iter2]);

DESCRIPTION

       The Attean::IteratorSequence class represents a typed iterator that is backed by zero or
       more sub-iterators. When iterated over, it will return all the elements of all of its sub-
       iterators, in order, before returning undef.  It conforms to the Attean::API::Iterator
       role.

       The Attean::IteratorSequence constructor requires two named arguments:

       iterators
           An array reference containing zero or more Attean::API::Iterator objects.

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

METHODS

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

       "push( $iterator )"
           Adds the new $iterator to the end of the array of sub-iterators.

           After this call, $iterator will be owned by the IteratorSequence, so making any method
           calls on $iterator after this point may produce unexpected results.
