| * Data Structure overview |
| * There are 4 global STL(' maps |
| * cbMap -- map of command Buffer (CB) objects to MT_CB_INFO structures |
| * Each MT_CB_INFO struct has an stl list container with |
| * memory objects that are referenced by this CB |
| * memObjMap -- map of Memory Objects to MT_MEM_OBJ_INFO structures |
| * Each MT_MEM_OBJ_INFO has two stl list containers with: |
| * -- all CBs referencing this mem obj |
| * -- all VK Objects that are bound to this memory |
| * objectMap -- map of objects to MT_OBJ_INFO structures |
| * |
| * Algorithm overview |
| * These are the primary events that should happen related to different objects |
| * 1. Command buffers |
| * CREATION - Add object,structure to map |
| * CMD BIND - If mem associated, add mem reference to list container |
| * DESTROY - Remove from map, decrement (and report) mem references |
| * 2. Mem Objects |
| * CREATION - Add object,structure to map |
| * OBJ BIND - Add obj structure to list container for that mem node |
| * CMB BIND - If mem-related add CB structure to list container for that mem node |
| * DESTROY - Flag as errors any remaining refs and remove from map |
| * 3. Generic Objects |
| * MEM BIND - DESTROY any previous binding, Add obj node w/ ref to map, add obj ref to list container for that mem node |
| * DESTROY - If mem bound, remove reference list container for that memInfo, remove object ref from map |
