| michael@0 | 32 | // StaticAddressMap is a wrapper class of StaticMap, just as AddressMap wraps |
| michael@0 | 33 | // std::map. StaticAddressMap provides read-only Retrieve() operation, similar |
| michael@0 | 34 | // as AddressMap. However, the difference between StaticAddressMap and |
| michael@0 | 35 | // AddressMap is that StaticAddressMap does not support dynamic operation |
| michael@0 | 36 | // Store() due to the static nature of the underlying StaticMap. |
