Package io.apicurio.registry.utils.converter

Class SerdeBasedConverter<S,T>

java.lang.Object

io.apicurio.registry.utils.converter.SerdeBasedConverter<S,T>

All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.kafka.connect.storage.Converter

Direct Known Subclasses:

AvroConverter

public class SerdeBasedConverter<S,T>
extends Object
implements org.apache.kafka.connect.storage.Converter, Closeable

Very simplistic converter that delegates most of the work to the configured serializer and deserializer. Subclasses should override applySchema(Schema, Object) and provideSchema(T) or toSchemaAndValue(T).
