README

Harbinger\Iterator is a library for collection control. It's loosely based on typed lists from strongly typed languages (such Java, C#, etc.).

Requirements

• PHP 7.0+ (Version 2.0.0 or earlier)
• PHP 5.6+ (Version 1.x.x)

Installation

Package avaible at Packgist

composer.json

#!json
{
    "require": {
        "harbinger/iterator": "@stable",
    }
}

Usage

As a simple object typed list (eg.: Connection list)

#!php
$collection = new \Harbinger\Iterator\Collection\Object(\Connection::class);

$collection->add(new \Connection('pgsql'));
$collection->add(new \Connection('mysql'));

foreach($collection AS $connection) {

}

This implementation kind doesn't need any other implementation, but cannot be type hinted for a specified collection list.

Must be validate with \Harbinger\Iterator\Collection::getTargetClass().

#!php
$collection->getTargetClass() === \Connection::class;

As a modeled object typed list (eg.: Connection list)

#!php
namespace Collection;

class Connection extends \Harbinger\Iterator\Collection {

    /**
     * {@inheritdoc}
     **/
    public function getTargetClass() {
        return \Contato::class;
    }
}

#!php
$collection = new \Collection\Connection();

$collection->add(new \Connection('pgsql'));
$collection->add(new \Connection('mysql'));

foreach($collection AS $connection) {

}

Must be implemented for the specified object. Can use type hint:

#!php
public function setCollection(\Collection\Connection $collection) {

}
