Method Detail

status

GrpcServerResponse<Req,Resp> status(GrpcStatus status)

Set the grpc status response

Parameters:

status - the status

Returns:

a reference to this, so the API can be used fluently

statusMessage

GrpcServerResponse<Req,Resp> statusMessage(String msg)

Set the grpc status response message

Parameters:

msg - the message

Returns:

a reference to this, so the API can be used fluently

encoding

GrpcServerResponse<Req,Resp> encoding(String encoding)

Description copied from interface: GrpcWriteStream

Set the stream encoding, e.g. identity or gzip. It must be called before sending any message, otherwise identity will be used.

Specified by:

encoding in interface GrpcWriteStream<Req>

Parameters:

encoding - the target message encoding

Returns:

a reference to this, so the API can be used fluently

trailers

MultiMap trailers()

Returns:

the MultiMap to write metadata trailers

exceptionHandler

GrpcServerResponse<Req,Resp> exceptionHandler(Handler<Throwable> handler)

Description copied from interface: WriteStream

Set an exception handler on the write stream.

Specified by:

exceptionHandler in interface GrpcWriteStream<Req>

Specified by:

exceptionHandler in interface StreamBase

Specified by:

exceptionHandler in interface WriteStream<Req>

Parameters:

handler - the exception handler

Returns:

a reference to this, so the API can be used fluently

setWriteQueueMaxSize

GrpcServerResponse<Req,Resp> setWriteQueueMaxSize(int maxSize)

Description copied from interface: WriteStream

Set the maximum size of the write queue to maxSize. You will still be able to write to the stream even if there is more than maxSize items in the write queue. This is used as an indicator by classes such as Pipe to provide flow control.

The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

Specified by:

setWriteQueueMaxSize in interface GrpcWriteStream<Req>

Specified by:

setWriteQueueMaxSize in interface WriteStream<Req>

Parameters:

maxSize - the max size of the write stream

Returns:

a reference to this, so the API can be used fluently

drainHandler

GrpcServerResponse<Req,Resp> drainHandler(Handler<Void> handler)

Description copied from interface: WriteStream

Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.

The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.

Specified by:

drainHandler in interface GrpcWriteStream<Req>

Specified by:

drainHandler in interface WriteStream<Req>

Parameters:

handler - the handler

Returns:

a reference to this, so the API can be used fluently

send

default Future<Void> send(Resp item)

send

default Future<Void> send(ReadStream<Resp> body)
