Class: KVMultiplex::Providers::Memory

Inherits:
KVMultiplex::Provider show all
Defined in:
lib/kvmultiplex/providers/memory.rb

Overview

The ‘Memory` provider just stores a list of potential values. Since other providers are sparse trees (there’s no “list” operation), we’re just going to store values as complete subkeys, stringified internally to avoid accidentally changing a subkey further down the line.
