A set of interfaces in PHP for storing and manipulating a collection of objects.

- [LinkedList](./src/List/LinkedList.php) A double linked list implementation, *add* is an O(1) operation.
- [ArrayList](./src/List/ArrayList.php) An array backed list gaurantees *set* and *get* by index are O(1) operations, *unset* is O(n).
- [Stack](./src/Stack/Stack.php) A double linked list backed LIFO structure, *push*, *pop* and *peek* are all O(1).
- [Queue](./src/Queue/Queue.php) A double linked list backed FIFO structure, *queue*, *dequeue* and *peek* are all O(1).

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

[](#installation)

```
composer require sokumar2/collections
```

Usage
-----

[](#usage)

### Linked List

[](#linked-list)

You can get an instance of a LinkedList from its factory by calling the `createInstance` method. This ensures that only a concrete implementation of ListInterface is created.

```
$listFactory = new LinkedListFactory();

$linkedList = $listFactory->createInstance();
```

### Laravel

[](#laravel)

When using in a Laravel application, you can define the list service as follows (if not taking help of the provided factory method) to ensure that the instantiation is again tied to its implementation.

```
class ListServiceProvider extends ServiceProvider implements DeferrableProvider
{
    public function register(): void
    {
        $this->app->bind(ListInterface::class, LinkedList::class);
    }

    public function provides(): array
    {
        return [
            ListInterface::class
        ];
    }
}
```

Tests
-----

[](#tests)

```
composer run test
```

For coverage report, make sure you have xdebug extenstion installed.

```

```
