This library ports the Java Collections Framework to PHP.

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

[](#installation)

```
composer require tebru/php-collections

```

Collections
-----------

[](#collections)

Collections provide data storage where order and random access do not matter. All collections implement `CollectionInterface`.

### AbstractCollection

[](#abstractcollection)

This is an abstract class that implements the methods it can. It defers the decision of what underlying data structure to use to the concrete implementation.

### Bag

[](#bag)

This is an implementation of `CollectionInterface` that extends from `AbstractCollection` and uses an array as data storage.

### AbstractList

[](#abstractlist)

This inherits from `AbstractCollection` and implements the `ListInterface`. Lists add random access to collections. The allow getting/setting/removing at a specific index. By default, they add elements to the end of the list.

### ArrayList

[](#arraylist)

This is an implementation of `CollectionInterface` and `ListInterface`. It extends from `AbstractList` and uses an array as data storage.

### AbstractSet

[](#abstractset)

This extends from `AbstractCollection` and implements `SetInterface`. Sets differ from generic collections by only allowing one of each element.

### HashSet

[](#hashset)

This is an implementation of `CollectionInterface` and `SetInterface` and extends from `AbstractSet`. This uses a `HashMap` as data storage.

Maps
----

[](#maps)

Maps provide data storage where order does not matter, but the ability to get a value by key is important. All maps implement `MapInterface`.

### AbstractMap

[](#abstractmap)

This implements `MapInterface` and implements any methods that do not need to know about the specific data storage.

### HashMap

[](#hashmap)

This is an implementation of `MapInterface` and extends from `AbstractMap`. It uses an array as data storage.
