From c10c61449f954702ae6d8092120321744acd82ff Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 4 Feb 2016 14:28:26 +0100 Subject: Eliminate the "store" global variable Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref, 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.) --- src/nix-store/xmlgraph.hh | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/nix-store/xmlgraph.hh') diff --git a/src/nix-store/xmlgraph.hh b/src/nix-store/xmlgraph.hh index c2216c5a4627..6d6d12a066d5 100644 --- a/src/nix-store/xmlgraph.hh +++ b/src/nix-store/xmlgraph.hh @@ -4,6 +4,8 @@ namespace nix { -void printXmlGraph(const PathSet & roots); +class StoreAPI; + +void printXmlGraph(StoreAPI & store, const PathSet & roots); } -- cgit 1.4.1
