# Cache::Ref::Null(3pm)

Caches nothing

## NAME

Cache::Ref::Null - Caches nothing

## SYNOPSIS

```
    # useful for comparing the effect of a cache compared to no
    # caching without code changes:
    my $c = Cache::Profile::Compare->new(
        caches => [
            Cache::Ref::Foo->new( ... ),
            Cache::Ref->Null->new,
        ],
    );
```

## DESCRIPTION

This cache implementation will cache nothing.

This is primarily intended for testing or comparing runtime without a cache against runtime with a cache.

It's like Cache::Null but supports the additional methods in Cache::Ref.
