class Puppet::Util::Storage

cache(object) click to toggle source

Return a hash that will be stored to disk. It’s worth noting here that we use the object’s full path, not just the name/type combination. At the least, this is useful for those non-isomorphic types like exec, but it also means that if an object changes locations in the configuration it will lose its cache.
