Generic collection (Under development)

Strongly typed generic collection implementation

Installation

Use composer to install:

composer require kartavik/typed-collection

Usage

Dynamic

• internal types

<?php

use kartavik\Support\Collection;
use kartavik\Support\Strict;

$items = [1, 2, 3, 4,];
$collection = new Collection(Strict::integer(), $items); // Return instance of typed collection
$collection = Collection::{'integer'}($items); // Work same as constructor

// Another examples

// string
Collection::{Strict::STRING}(['str1', 'str2']);

// float
Collection::{Strict::FLOAT}([12.3, 23.5, 3., 54.321,]);

// array
Collection::{Strict::ARRAYABLE}([[1, 2], ['str1'], [123.456]]);

// boolean
Collection::{Strict::BOOLEAN}([true, false]);

// object
Collection::{Strict::OBJECT}([new stdClass(), new Exception()]);

• User types

<?php

use kartavik\Support\Collection;
use kartavik\Support\Strict;

// You can put name of class to static call
// In this case collection can take only stdClass
// It will work with any declared classes
$collection = Collection::{stdClass::class}([]);

// you can also do it with constructor
$collection = new Collection(Strict::object(stdClass::class), []);

// Strict class also support static call for class name
$strict = Strict::{stdClass::class}();
$collection = new Collection($strict, []);

Extend

StringCollection.php:

<?php

use kartavik\Support;

class StringCollection extends Support\Collection
{
    public function __construct(array $items)
    {
        // do something
        
        parent::__construct(Support\Strict::string(), $items);
    }
}

Where is strong type?

Class Strict help collection to validate type of elements;

If you will try in any moment put to the collection element that is not of element type you will get Exception\Validation

If you will try set some specific type you will catch Exception\UnprocessedType
