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