Interface Serde<T>

public interface Serde<T>

Interface defining serialization and deserialization of concrete types.

You can create a custom one using using(String, ThrowingFunction, ThrowingFunction).

Method Summary

Modifier and Type	Method	Description
default @Nullable java.lang.String	contentType()	Content-type to use in request/responses.
T	deserialize(byte[] value)
default T	deserialize(com.google.protobuf.ByteString byteString)
byte[]	serialize(@Nullable T value)
default com.google.protobuf.ByteString	serializeToByteString(@Nullable T value)
static <T> Serde<T>	using(ThrowingFunction<T,byte[]> serializer, ThrowingFunction<byte[],T> deserializer)	Like using(String, ThrowingFunction, ThrowingFunction), using content-type application/octet-stream.
static <T> Serde<T>	using(java.lang.String contentType, ThrowingFunction<T,byte[]> serializer, ThrowingFunction<byte[],T> deserializer)	Create a Serde from serializer/deserializer lambdas, tagging with contentType.
static <T> Serde<T>	withContentType(java.lang.String contentType, Serde<T> inner)

Method Detail

serialize

byte[] serialize(@Nullable T value)

serializeToByteString

default com.google.protobuf.ByteString serializeToByteString(@Nullable T value)

deserialize

T deserialize(byte[] value)

deserialize

default T deserialize(com.google.protobuf.ByteString byteString)

contentType

default @Nullable java.lang.String contentType()

Content-type to use in request/responses.

If null, the SDK assumes the produced output is empty. This might change in the future.

using

static <T> Serde<T> using(ThrowingFunction<T,byte[]> serializer,
                          ThrowingFunction<byte[],T> deserializer)

Like using(String, ThrowingFunction, ThrowingFunction), using content-type application/octet-stream.

using

static <T> Serde<T> using(java.lang.String contentType,
                          ThrowingFunction<T,byte[]> serializer,
                          ThrowingFunction<byte[],T> deserializer)

Create a Serde from serializer/deserializer lambdas, tagging with contentType. Before invoking the serializer, we check that value is non-null.

withContentType

static <T> Serde<T> withContentType(java.lang.String contentType,
                                    Serde<T> inner)
