Attean::IteratorSequence - Iterator implementation backed by zero or more sub-iterators
This document describes Attean::IteratorSequence version 0.004_01
use v5.14; use Attean; my $iter = Attean::IteratorSequence->new(iterators => [$iter1, $iter2]);
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:
An array reference containing zero or more Attean::API::Iterator objects.
A string representing the type of the items that will be returned from the iterator.
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.
$iterator
After this call, $iterator will be owned by the IteratorSequence, so making any method calls on $iterator after this point may produce unexpected results.
