com.google.protobuf.MapField< K, V >.StorageMode Enum Reference

Detailed Description

Indicates where the data of this map field is currently stored.

• MAP: Data is stored in mapData.
• LIST: Data is stored in listData.
• BOTH: mapData and listData have the same data.

When the map field is accessed (through generated API or reflection API), it will shift between these 3 modes:

         getMap()   getList()    getMutableMap()   getMutableList()
MAP      MAP        BOTH         MAP               LIST
LIST     BOTH       LIST         MAP               LIST
BOTH     BOTH       BOTH         MAP               LIST

As the map field changes its mode, the list/map reference returned in a previous method call may be invalidated.
