Version
-------

[](#version)

**Release 1.0.0**

Why?
----

[](#why)

Adds an internal cache with a memoize interface. Creates a cache of results based on a hash of the arguments used for the call.

Setup
-----

[](#setup)

```
$ composer require pinkcrab/memoize-trait
```

```
use PinkCrab\Memoize\Memoizable;

class CategoryRepository {

    /**
     * Gives access to the Memoize cache
     */
    use Memoizable;

    /**
     * Will call the database on the first call.
     * Creates a cache based on the hash of $id & $parent (concatinated)
     */
    public function getCategory($id, $parent): ?CategoryTerm {
        return $this->memoize(
            $this->generateHash($id, $parent),
            function () use ($id, $parent): ?CategoryTerm {
                return $this->slowDataSource->someExpensiveQuery($id, $parent);
            }
        )
    }
}
```

Methods
-------

[](#methods)

### memoize( string $hash, callable $fetch ): mixed

[](#memoize-string-hash-callable-fetch--mixed)

The hash value should be unique and repeatable/pure, based on the parameters. You can use the built in generateHash(...$scarla). The callable passed, should carry out your operation, before the result is returned, it is passed to the internal cache.

```
public function doExpensiveCall($param1, $param2): Result
{
    return $this->memoize(
        // Generate Hash
        $this->generateHash($param1, $param2),
        // The fetch/call callable.
        function() use ($param1, $param2) : Result {
            return $this->service
                ->expensiveCall($param1, $param2);
        }
    );
}
```

### generateHash(...$parts): string

[](#generatehashparts-string)

Allows the passing of any number of serializable variables and being returned a repeatable hash. This only uses MD5 under the hood, you can create a custom hash generator

### flushMemoize(): void

[](#flushmemoize-void)

Clears the internal cache array.
