    unless namespace.is_a?(Namespace)
        raise "Invalid class for a namespace: #{namespace.class}"
    end
    @namespace = namespace
    unless runner_proc || finisher_proc then
        raise "An accesser must have at least a reading or a writing procedure."
    end
    @runner_proc  = runner_proc ? runner_proc.to_proc : proc { }
    @finisher_proc  = finisher_proc ? finisher_proc.to_proc : proc { }
    @reseter_proc = reseter_proc ? reseter_proc.to_proc : proc {}
