+// MapEntry is the returned google::protobuf::Message when calling AddMessage of
+// google::protobuf::Reflection. In order to let it work with generated message
+// reflection, its in-memory type is the same as generated message with the same
+// fields. However, in order to decide the in-memory type of key/value, we need
+// to know both their cpp type in generated api and proto type. In
+// implementation, all in-memory types have related wire format functions to
+// support except ArenaStringPtr. Therefore, we need to define another type with
+// supporting wire format functions. Since this type is only used as return type
+// of MapEntry accessors, it's named MapEntry accessor type.
+//
+// cpp type:               the type visible to users in public API.
+// proto type:             WireFormatLite::FieldType of the field.
+// in-memory type:         type of the data member used to stored this field.
+// MapEntry accessor type: type used in MapEntry getters/mutators to access the
+//                         field.
