Cacheable – A transparent caching library
=========================================

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

[](#installation)

Using [composer](https://getcomposer.org/download/):

```
composer require sci/cacheable

```

Usage
-----

[](#usage)

Lets say, you have a class `Foo`, implementing a method `Foo::bar()` with quite high time/resource consumption:

```
class Foo
{
    public function bar($a, $b)
    {
        // make some hard things with $a and $b
        ...

        return ...; // some result
    }
}

$foo = new Foo();

$bar = $foo->bar(1, 2); // takes some amount of time

// and later, again...
$bar = $foo->bar(1, 2); // takes the same amount of time, again
```

If there are no side-effects, the result of `Foo::bar()` is determined only by its arguments `$a` and `$b`. So you could use some cache, if eventuelly the method is called again. To avoid messing around with cache keys, you can use `sci\cacheable`:

```
use Sci\Cacheable;
use Sci\CacheTrait;

class Foo implements Cacheable
{
    use CacheTrait;

    public function bar($a, $b)
    {
        // make some hard things with $a and $b
        ...

        return ...; // some result
    }
}

$foo = new Foo();
$foo->setCache(/* any PSR-6 cache pool interface */)

$bar = $foo->cache()->bar(1, 2); // 1st call takes some time, but now, the result is stored into cache

// and later, again...
$bar = $foo->cache()->bar(1, 2); // 2nd call's result comes directly from cache
```

### en détail

[](#en-détail)

- A class to be cached (`Foo` in example above) implements the interface [`Sci\Cacheable`](lib/Cacheable.php) (which demands a method `cache()`).
- This can be done using [`Sci\CacheTrait`](lib/CacheTrait.php) (which additially provides a method `setCache()`).
- The method `setCache` gets as first argument a service, implementing [`Psr\Cache\CacheItemPoolInterface`](https://github.com/php-fig/cache/blob/master/src/CacheItemPoolInterface.php).
    - This cache pool is the actual cache backend.
    - An optional second argument to `setCache` is the default TTL (*time to live*) for all cached values.
- To use the cache, method calls are *proxied* through the method `cache()`, e.g. instead of `$foo->bar(1, 2)`, now we use `$foo->cache()->bar(1, 2)`.
    - Method `cache()` returns `$this`, i.e. it acts in a transparent way (fluent interface).
    - An optional argument for `cache()` allows to specify a TTL, different from the default one.
