|
38 kumpf 1.13 // Zeros(): fills memory with zeros.
39 // Destroy(): destructs multiple objects in contiguous memory.
40 // CopyToRaw(): copies multiple objects to raw memory.
41 // InitializeRaw(): default constructs mulitple object over raw memory.

43 kumpf 1.13 // Each of these is a template but specializations are provide for
44 // efficiency (which in some cases removes uncessary loops).
