Eelco Dolstra	fa7cd5369b	StoreAPI -> Store ... Calling a class an API is a bit redundant...	2016-02-04 14:48:42 +01:00
Eelco Dolstra	c10c61449f	Eliminate the "store" global variable ... Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)	2016-02-04 14:28:26 +01:00
