Componenta Iterator
===================

[](#componenta-iterator)

Iterator utilities for replayable iteration, reverse traversal, string traversal, and array conversion.

Use this package when a library needs iterator behavior without depending on collection frameworks.

Installation
------------

[](#installation)

```
composer require componenta/iterator
```

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`componenta/stream-iterator`Prefer it for large PSR-7 streams because it keeps only the current chunk in memory.`componenta/arrayable`Some iterators expose `toArray()` for array conversion.ReplayableIterator
------------------

[](#replayableiterator)

`ReplayableIterator` wraps arrays, iterators, iterator aggregates, and generators. It caches traversed values so a one-shot source can be iterated again.

```
use Componenta\Stdlib\ReplayableIterator;

$iterator = new ReplayableIterator((function () {
    yield 'a' => 1;
    yield 'b' => 2;
})());

$iterator->toArray(preserveKeys: true); // ['a' => 1, 'b' => 2]
```

Calling `count()` or `toArray()` forces full traversal of the wrapped source.

Reverse Iteration
-----------------

[](#reverse-iteration)

`ReverseIterator` iterates an iterable in reverse order. It materializes values internally, so it is intended for finite iterables.

`ArrayListReverseIterator` is a small reverse iterator for list arrays.

StringIterator
--------------

[](#stringiterator)

`StringIterator` iterates over a string with encoding support and cursor helpers:

- `moveTo()`
- `forward()`
- `backward()`
- `read()`
- `remaining()`
- `peek()`

Array Conversion
----------------

[](#array-conversion)

`IteratorToArray` exposes a `toArray()` contract for iterator classes that can materialize their contents.

Memory Notes
------------

[](#memory-notes)

Replayable and reverse iterators trade memory for traversal behavior. They are appropriate for finite sequences. For large PSR-7 streams, use `componenta/stream-iterator`, which keeps only the current chunk.
