31 // Memory.h
32 //
33 // This file contains assorted memory-oriented routines:
34 //
35 // Zeros(): fills memory with zeros.
36 // Destroy(): destructs multiple objects in contiguous memory.
37 // CopyToRaw(): copies multiple objects to raw memory.
38 // InitializeRaw(): default constructs mulitple object over raw memory.
39 //
40 // Each of these is a template but specializations are provide for
41 // efficiency (which in some cases removes uncessary loops).
