module Backend
    # This is a basic backend for key value stores. It receives on
    # initialization the store, which should respond to three methods:
    #
    # * store#[](key)         - Used to get a value
    # * store#[]=(key, value) - Used to set a value
    # * store#keys            - Used to get all keys
    #
    # Since these stores only supports string, all values are converted
    # to JSON before being stored, allowing it to also store booleans,
    # hashes and arrays. However, this store does not support Procs.
    #
    # As the ActiveRecord backend, Symbols are just supported when loading
    # translations from the filesystem or through explicit store translations.
    #
    # Also, avoid calling I18n.available_locales since it's a somehow
    # expensive operation in most stores.
    #
    # == Example
    #
    # To setup I18n to use TokyoCabinet in memory is quite straightforward:
    #
    #   require 'rufus/tokyo/cabinet' # gem install rufus-tokyo
    #   I18n.backend = I18n::Backend::KeyValue.new(Rufus::Tokyo::Cabinet.new('*'))
    #
    # == Performance
    #
    # You may make this backend even faster by including the Memoize module.
    # However, notice that you should properly clear the cache if you change
    # values directly in the key-store.
    #
    # == Subtrees
    #
    # In most backends, you are allowed to retrieve part of a translation tree:
    #
    #   I18n.backend.store_translations :en, :foo => { :bar => :baz }
    #   I18n.t "foo" #=> { :bar => :baz }
    #
    # This backend supports this feature by default, but it slows down the storage
    # of new data considerably and makes hard to delete entries. That said, you are
    # allowed to disable the storage of subtrees on initialization:
    #
    #   I18n::Backend::KeyValue.new(@store, false)
    #
    # This is useful if you are using a KeyValue backend chained to a Simple backend.
