AbstractMessage
Implements MapEntry messages.
In reflection API, map fields will be treated as repeated message fields and each map entry is accessed as a message. This MapEntry class is used to represent these map entry messages in reflection API.
Protobuf internal. Users shouldn't use this class.

Create a default MapEntry instance. A default MapEntry instance should be created only once for each map entry message type. Generated code should store the created default instance and use it later to create new MapEntry messages of the same type.

getSerializedSize()

getSerializedSize
()
Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.
If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.
