- // static_address_map.h: StaticAddressMap.
- //
- // StaticAddressMap is a wrapper class of StaticMap, just as AddressMap wraps
- // std::map. StaticAddressMap provides read-only Retrieve() operation, similar
- // as AddressMap. However, the difference between StaticAddressMap and
- // AddressMap is that StaticAddressMap does not support dynamic operation
- // Store() due to the static nature of the underlying StaticMap.
- //
- // See address_map.h for reference.
