Method Detail

toGrpcSpringMessage

public static GrpcSpringMessage toGrpcSpringMessage(byte[] payload,
                                                    Map<String,String> headers)

toGrpcSpringMessage

public static GrpcSpringMessage toGrpcSpringMessage(org.springframework.messaging.Message<byte[]> message)

fromGrpcSpringMessage

public static org.springframework.messaging.Message<byte[]> fromGrpcSpringMessage(GrpcSpringMessage message)

requestReply

public static org.springframework.messaging.Message<byte[]> requestReply(org.springframework.messaging.Message<byte[]> inputMessage)

requestReply

public static org.springframework.messaging.Message<byte[]> requestReply(String host,
                                                                         int port,
                                                                         org.springframework.messaging.Message<byte[]> inputMessage)

biStreaming

public static reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> biStreaming(reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)

Utility method to support bi-directional streaming interaction. Will connect to gRPC server using default host/port, otherwise use biStreaming(String, int, Flux) method. Keep in mind that there is no implied relationship between input stream and output stream. They are completely independent where one may end before the other.

Parameters:

inputStream - FluxMessage<byte[]>> representing input stream.

Returns:

Flux<Message<byte[]>> representing output stream

biStreaming

public static reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> biStreaming(String host,
                                                                                                     int port,
                                                                                                     reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)

Utility method to support bi-directional streaming interaction. Keep in mind that there is no implied relationship between input stream and output stream. They are completely independent where one may end before the other.

Parameters:

host - gRPC server host name

port - gRPC server port

inputStream - FluxMessage<byte[]>> representing input stream

Returns:

Flux<Message<byte[]>> representing output stream

serverStream

public static reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> serverStream(String host,
                                                                                                      int port,
                                                                                                      org.springframework.messaging.Message<byte[]> inputMessage)

clientStream

public static org.springframework.messaging.Message<byte[]> clientStream(reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)

Utility method to support client-side streaming interaction. Will connect to gRPC server using default host/port, otherwise use clientStream(String, int, Flux) method.

Parameters:

inputStream - FluxMessage<byte[]>> representing input stream.

Returns:

Message<byte[]> representing output

clientStream

public static org.springframework.messaging.Message<byte[]> clientStream(String host,
                                                                         int port,
                                                                         reactor.core.publisher.Flux<org.springframework.messaging.Message<byte[]>> inputStream)

Utility method to support client-side streaming interaction.

Parameters:

host - gRPC server host name

port - gRPC server port

inputStream - FluxMessage<byte[]>> representing input stream

Returns:

Message<byte[]> representing output
