typed collections

What is this?

This is a very simple way to make arrays type hinted!

$list = new UserCollection(new User());

OK

$list = new UserCollection('User');

Will throw:

VistikExceptionInvalidTypeException: Item (string) 'User' is not a VistikExampleUser object!

Install

Run composer require vistik/typed-collections

Use build in Collections for primitives

Out-of-the-box collections for:

• Booleans
• Integers
• Floats
• Strings
• Emails
• Numbers (float or int)

They can be created with out-of-the-box laraval style helpers:

• bCollect([true, false]) - To create a BoolCollection
• iCollect([1, 2, 3, 4]) - To create a IntegerCollection
• fCollect([3.14, 22/7, 6.66]) - To create a FloatCollection
• sCollect(['hello', 'world'']) - To create a StringCollection
• eCollect(['[email protected]', '[email protected]']) - To create a EmailCollection
• nCollect([1, 2, 3, 4, 3.14, INF]) - To create a NumberCollection

Do I have to create a type for each list? Yes, but

Look how easy it is:

use PhpsafariExampleUser;
class UserCollection extends TypedCollection{
    protected $type = User::class;
}

2 simple steps

1. Create a Class eg. AccountCollection extend TypedCollection
2. Just replace protected $type = 'VistikExampleUser'; with your class

or

If the check is more then just a is_a check, you can overwrite the function: isValidItem($item) in your new Collection class

Features

• Build upon IlluminateSupportCollection
