Interface ExtendedDeserializer<T>

Type Parameters:

T -

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, Deserializer<T>

All Known Implementing Classes:

ExtendedDeserializer.Wrapper

public interface ExtendedDeserializer<T>
extends Deserializer<T>

A Deserializer that has access to the headers associated with the record. Prefer Deserializer if access to the headers is not required. Once Kafka drops support for Java 7, the deserialize() method introduced by this interface will be added to Deserializer with a default implementation so that backwards compatibility is maintained. This interface may be deprecated once that happens. A class that implements this interface is expected to have a constructor with no parameters.
