30 // static_address_map.h: StaticAddressMap.
31 //
32 // StaticAddressMap is a wrapper class of StaticMap, just as AddressMap wraps
33 // std::map. StaticAddressMap provides read-only Retrieve() operation, similar
34 // as AddressMap. However, the difference between StaticAddressMap and
35 // AddressMap is that StaticAddressMap does not support dynamic operation
36 // Store() due to the static nature of the underlying StaticMap.
37 //
38 // See address_map.h for reference.
