Description
-----------

[](#description)

Typed collections are an implementation of typed lists. Collections allow us to have traversable lists of a predetermined type and its subtypes. Its behavior prevents the looseness of arrays in PHP.

This library contains four collection classes: mutable and immutable lists, and mutable and immutable dictionaries. Mutable lists/dictionaries have its internal array altered whenever we perform operations on it. Immutable lists/dictionaries generate a new instance of itself when operations are done on it.

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

[](#installation)

```
composer require edumarques/typed-collections:2.*

```

Basic usage
-----------

[](#basic-usage)

```
use EduardoMarques\TypedCollections\TypedCollection;
use EduardoMarques\TypedCollections\TypedCollectionImmutable;
use EduardoMarques\TypedCollections\Enum\ScalarType;
use EduardoMarques\TypedCollections\Enum\NonScalarType;

$typedCollection1 = TypedCollection::create(ScalarType::INTEGER);
$typedCollection2 = TypedCollection::create(ScalarType::STRING);

$typedCollectionImmutable1 = TypedCollectionImmutable::create(NonScalarType::CALLABLE);
$typedCollectionImmutable2 = TypedCollectionImmutable::create(\stdClass::class);
```

```
use EduardoMarques\TypedCollections\TypedDictionary;
use EduardoMarques\TypedCollections\TypedDictionaryImmutable;
use EduardoMarques\TypedCollections\Enum\ScalarType;
use EduardoMarques\TypedCollections\Enum\NonScalarType;

$typedDictionary1 = TypedDictionary::create(ScalarType::INTEGER, ScalarType::STRING);
$typedDictionary2 = TypedDictionary::create(ScalarType::STRING, ScalarType::DOUBLE);

$typedDictionaryImmutable1 = TypedDictionaryImmutable::create(ScalarType::INTEGER, NonScalarType::CALLABLE);
$typedDictionaryImmutable2 = TypedDictionaryImmutable::create(ScalarType::STRING, \stdClass::class);
```

Collection
----------

[](#collection)

A PHP implementation of an array list. Its type is specified at instantiation/construction. The class will perform runtime type checks to validate the appropriate values are being added. Many of the standard array functionalities are encapsulated in this class.

Dictionary
----------

[](#dictionary)

Dictionaries extend Collections' functionalities. The main difference is that they work with associative arrays, where you map keys to values.

Supported types:
----------------

[](#supported-types)

- `ScalarType::INTEGER`
- `ScalarType::STRING`
- `ScalarType::BOOLEAN`
- `ScalarType::DOUBLE`
- `NonScalarType::ARRAY`
- `NonScalarType::CALLABLE`
- `class-string`

Support for abstract classes and interfaces
-------------------------------------------

[](#support-for-abstract-classes-and-interfaces)

Collections and Dictionaries will check inheritance, so if you require a base class, derived classes can be added safely.
