# Attean::IteratorSequence(3pm)

Iterator implementation backed by zero or more sub-iterators

## NAME

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

## VERSION

This document describes Attean::IteratorSequence version 0.035

## 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.
