public annotation BuiltInTypeConverters
Flags to turn on/off extra type converters provided by Room.
For certain commonly used types (enums, UUID), Room provides automatic type converters. By default, these type converters are enabled but have lower priority than user provided type converters.
You can set these flags in the TypeConverters annotation to turn them off / on. It might be useful if you want to have more strict control over how these types are saved into the database.

Public methods
getByteBuffer
public final @NonNull BuiltInTypeConverters.State getByteBuffer()
Controls whether Room can generate a TypeConverter for java.nio.ByteBuffer and use its ByteBuffer representation while saving it into database.
By default, it is set to State.INHERITED (on by default unless set to another value in a higher scope).
getEnums
public final @NonNull BuiltInTypeConverters.State getEnums()
Controls whether Room can generate a TypeConverter for enum types and use their name() in the database.
By default, it is set to State.INHERITED (on by default unless set to another value in a higher scope).
getUuid
public final @NonNull BuiltInTypeConverters.State getUuid()
Controls whether Room can generate a TypeConverter for java.util.UUID and use its byte[] representation while saving it into database.
By default, it is set to State.INHERITED (on by default unless set to another value in a higher scope).
