Module: Mize::CacheProtocol

Included in:

DefaultCache

Defined in:

lib/mize/cache_protocol.rb

Overview

Marker interface for Mize-compatible cache backends.

A cache backend "is a" Mize::CacheProtocol simply by including this module. No methods are mandated — the module exists solely as a type tag that Mize can match against.

The primary consumer is Mize.cache_clear (see Mize::GlobalClear), which walks the heap with ObjectSpace.each_object(Mize::CacheProtocol) to locate every live cache instance and clear it. This is what turns a per-object cache into a globally clearable one without an explicit registry.

Examples:

A minimal compliant backend

class MyCache
  include Mize::CacheProtocol

  def read(name, options = nil) ... end
  def write(name, value, options = nil) ... end
  def clear(options = nil) ... end
end
