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.
