Classes
struct	llama::Copy< SrcMapping, DstMapping, SFINAE >
	Generic implementation of copy defaulting to fieldWiseCopy. LLAMA provides several specializations of this construct for specific mappings. Users are encouraged to also specialize this template with better copy algorithms for further combinations of mappings, if they can and want to provide a better implementation. More...
