Class MapFieldBuilder<KeyT, MessageOrBuilderT extends MessageOrBuilder, MessageT extends MessageOrBuilderT, BuilderT extends MessageOrBuilderT>

com.google.protobuf.MapFieldReflectionAccessor

com.google.protobuf.MapFieldBuilder<KeyT, MessageOrBuilderT, MessageT, BuilderT>

public class MapFieldBuilder<KeyT, MessageOrBuilderT extends MessageOrBuilder, MessageT extends MessageOrBuilderT, BuilderT extends MessageOrBuilderT>
extends MapFieldReflectionAccessor

Internal representation of map fields in generated builders.

This class supports accessing the map field as a Map to be used in generated API and also supports accessing the field as a List to be used in reflection API. It keeps track of where the data is currently stored and do necessary conversions between map and list.

This class is a protobuf implementation detail. Users shouldn't use this class directly.
