    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.
