widen

@Nonnull
public RecordSerializer<Message> widen()

Description copied from interface: RecordSerializer

Convert this typed record serializer to an untyped one.

• If this serializer wraps another serializer, for example, because it does compressions, then widen that serializer and return the result wrapped equivalently.
• If this serializer parses messages in a type-sensitive way, return the closest general purpose way.
• If this serializer is inherently bound to its type parameter, throw an exception.

If a FDBTypedRecordStore is created without calling FDBTypedRecordStore.Builder.setUntypedSerializer(com.apple.foundationdb.record.provider.common.RecordSerializer<com.google.protobuf.Message>), then in order to make the untyped record store that is paired with the typed store (used, for instance, to rebuild indexes), the given typed serializer will be widened by calling this method.

Specified by:

widen in interface RecordSerializer<Message>

Overrides:

widen in class MessageBuilderRecordSerializerBase<Message,Message,Message.Builder>

Returns:

a new serializer that works the same way but handles all record types.
