1.35 +// StaticAddressMap is a wrapper class of StaticMap, just as AddressMap wraps
1.36 +// std::map. StaticAddressMap provides read-only Retrieve() operation, similar
1.37 +// as AddressMap. However, the difference between StaticAddressMap and
1.38 +// AddressMap is that StaticAddressMap does not support dynamic operation
1.39 +// Store() due to the static nature of the underlying StaticMap.
1.40 +//
1.41 +// See address_map.h for reference.
