From c56d7fe0eba7905b0a63c4a1cfe909988653c23d Mon Sep 17 00:00:00 2001 From: kwolekr Date: Tue, 27 Oct 2015 02:51:43 -0400 Subject: Add DISABLE_CLASS_COPY macro (and use it) Use this macro to disallow copying of an object using the assignment operator or copy constructor. This catches otherwise silent-but-deadly mistakes such as "ServerMap map = env->getMap();" at compile time. If so desired, it is still possible to copy a class, but it now requires an explicit call to memcpy or std::copy. --- src/emerge.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/emerge.h') diff --git a/src/emerge.h b/src/emerge.h index 47ff218b8..a143b660f 100644 --- a/src/emerge.h +++ b/src/emerge.h @@ -164,6 +164,8 @@ private: bool popBlockEmergeData(v3s16 pos, BlockEmergeData *bedata); friend class EmergeThread; + + DISABLE_CLASS_COPY(EmergeManager); }; #endif -- cgit v1.2.3
