ClassBasedRegistry
==================

[](#classbasedregistry)

Allows to associate a value to one or more classes and then fetch this value by passing objects that implement these classes.

Usage
-----

[](#usage)

### Environment

[](#environment)

Let's assume that we have classes like these:

```
class Animal {}
class Elephant extends Animal {}
class Plant {}
```

To get a new instance of the registry create it:

```
$r = new \lukaszmakuch\ClassBasedRegistry\ClassBasedRegistry();
```

### Simple example

[](#simple-example)

Associate 42 with the Animal class:

```
$r->associateValueWithClasses(
    42,
    [Animal::class]
);
```

Fetch it by providing any animal...

```
$r->fetchValueByObjects([new Animal()]); //42
```

... that may be an elephant!

```
$r->fetchValueByObjects([new Elephant()]); //42
```

### Multiple classes

[](#multiple-classes)

It is possible to associate value with many classes:

```
$r->associateValueWithClasses(
    1970,
    [Animal::class, Plant::class]
);
```

While fetching objects may be passed in any order:

```
$r->fetchValueByObjects([new Plant(), new Elephant()]); //1970
```

### Throwing exceptions

[](#throwing-exceptions)

When it's not possible to obtain any value, then a \\lukaszmakuch\\ClassBasedRegistry\\Exception\\ValueNotFound exception is thrown:

```
try {
    $r->fetchValueByObjects([new Plant()]);
} catch (\lukaszmakuch\ClassBasedRegistry\Exception\ValueNotFound $e) {
  //it was not possible to fetch any value by a plant
}
```

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

[](#installation)

Use [composer](https://getcomposer.org) to get the latest version:

```
$ composer require lukaszmakuch/class-based-registry

```
