Interface ReaderSPI

public interface ReaderSPI

Interface for providing custom MapReader and ArrayReader implementations for a Reader to use when parsing native JSON or msgpack composite structures. This entry point exists to enable Transit libraries for other JVM languages to layer on top of the Java Transit library, but still get language-appropriate maps and arrays returned from a parse, while ensuring that parsing and decoding work correctly. This interface should never be used by applications that using this library.
