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

[](#installation)

Install with `composer require stratadox/entity-state`

What is this?
-------------

[](#what-is-this)

This package models the entity state at a certain point in the execution of the business logic.

The model is built in such a way that it can find differences in terms of added, altered or removed entities, when comparing itself to another point in the process.

Additionally, the package comes with a service to extract the state of the entities.

How to use this?
----------------

[](#how-to-use-this)

Step 1: Extract the state of the entities from the [`Identity Map`](https://github.com/Stratadox/IdentityMap).

```
$originalState = Extract::state()->from($identityMap);
```

Step 2: Make some changes in the domain.

```
$identityMap = $identityMap->add('id-26', new Something('foo'));

$identityMap->get(User::class, '1')->changeNameTo('Chuck Norris');

$identityMap = $identityMap->remove(Foo::class, '3');
```

(Note: In real life you'd access the identity map through repositories instead)

Step 3: Extract the new state from the entities in the identity map.

```
$newState = Extract::state()->from($identityMap);
```

Step 4: Get the changes since the original state was captured.

```
$changes = $newState->changesSince($originalState);
```

Step 5: Profit.

```
assert($changes->added()[0]->class() === Something::class);
assert($changes->added()[0]->id() === 'id-26');

assert($changes->altered()[0]->class() === User::class);
assert($changes->altered()[0]->id() === '1');

assert($changes->removed()[0]->class() === Foo::class);
assert($changes->removed()[0]->id() === '3');

assert($changes->altered()[0]->properties()[0]->name() === 'userName');
assert($changes->altered()[0]->properties()[0]->value() === 'Chuck Norris');
```

### Name formatting

[](#name-formatting)

Notice that in the above example, the user's name is stored as a string value in the property `userName`. If instead the `User` class would have a `Name` value object, the assertion would look more like this:

```
assert($changes->altered()[0]->properties()[0]->name() === 'Name:userName.name');
```

If this `Name` object were contained in an array, the result would look like this:

```
assert($changes->altered()[0]->properties()[0]->name() === 'Name:array:userName[0].name');
```

### Value formatting

[](#value-formatting)

It may in some cases be preferable to store the string representation of an instance, rather than all its properties. To extract a string representation of the objects of a class, one can use:

```
$entityState = Extract::stringifying(UuidInterface::class)->from($identityMap);
```

To do
-----

[](#to-do)

Potential to-do's:

- Increase performance by hashing properties names?
- Split names into parts?
- Add methods for querying properties?
- Make properties exportable for hydration
