NAME

Cache::Ref::Null

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.
