Type Enforcement
================

[](#type-enforcement)

If you've ever come across a time where you're writing loosely-coupled code but want to check a parameters type at the start of a method, then this library is for you.

How you're probably doing it
----------------------------

[](#how-youre-probably-doing-it)

```
class UserRegistrar {
    public function register(array $usersDetails, $author)
    {
        if (!$author instanceof SomeAuthor) {
            throw new \InvalidArgumentException('The author must be an instance of SomeAuthor');
        }
    }
}
```

Let's refactor!
---------------

[](#lets-refactor)

```
use Joshbrw\TypeEnforcement\Type;

class UserRegistrar {
    public function register(array $usersDetails, $author)
    {
        /* Throws \InvalidArgumentException on invalid input */
        Type::enforce($author, SomeAuthor::class);
    }
}
```

Custom Exception Messages
-------------------------

[](#custom-exception-messages)

By default the package will provide a useful exception message, stating which type is expected and which type has been provided, i.e:

```
Expected [Tests\NonExistentClass], [array '["array"]'] provided.

```

This exception message can be switched out by providing a custom message as the third parameter, i.e.:

```
Type::enforce($variable, Type::class, 'The variable must be a Type!');
```

Not a fan of static method calls?
---------------------------------

[](#not-a-fan-of-static-method-calls)

This package also includes a helper method that accepts the same parameters:

```
enforce_type($variable, Type::class, 'The variable must be a Type!');

```
