public NettyOcientWireV1Transport(io.netty.channel.ChannelFuture channelFuture,
 Supplier<CompletionStage<Void>> onClose)

Method Details

getLocalAddress

public Optional<SocketAddress> getLocalAddress()

Specified by:

getLocalAddress in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

getRemoteAddress

public Optional<SocketAddress> getRemoteAddress()

Specified by:

getRemoteAddress in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

hasData

public boolean hasData()

stream

public com.ibm.asyncutil.iteration.AsyncIterator<SimplexTransport.StreamCtx<TransportResult<io.netty.buffer.ByteBuf>>> stream(com.ibm.asyncutil.iteration.AsyncIterator<SimplexTransport.StreamCtx<TransportResult<io.netty.buffer.ByteBuf>>> requests,
 int queueDepth)

Description copied from interface: SimplexTransport

Accepts a stream of requests and returns the result response stream. Backpressure may be applied by the request producer via the

invalid reference

Asynciterator

interface.

Implementations may enqueue up to maxQueueDepth requests in the recepient's recv queue at any given time.

Implementations must ensure that requests are sent in the sequence they are generated.

Specified by:

stream in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

Parameters:

requests - the stream of SimplexTransports. Callers may apply backpressure by throttling the stream of requests.

queueDepth - the maximum queue depth of the recipient's recv queue.

Returns:

the stream of responses; one per request.

sendAndReceive

public CompletionStage<TransportResult<io.netty.buffer.ByteBuf>> sendAndReceive(io.netty.buffer.ByteBuf request,
 SimplexTransport.Ctx ctx)

Description copied from interface: SimplexTransport

Sends a SimplexTransport to the server and returns a CompletionStage that completes with the SimplexTransport from the server.

Specified by:

sendAndReceive in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

Parameters:

request - the SimplexTransport

Returns:

a CompletionStage that completes with a SimplexTransport from the server.

sendNoReceive

public CompletionStage<TransportResult<Void>> sendNoReceive(io.netty.buffer.ByteBuf request,
 SimplexTransport.Ctx ctx)

Description copied from interface: SimplexTransport

Sends SimplexTransport to the server. notably, a response is NOT expected from the server.

Specified by:

sendNoReceive in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

Parameters:

request - the SimplexTransport

allocate

public io.netty.buffer.ByteBuf allocate(int capacity)

Description copied from interface: SimplexTransport

Allocates an I/O capable ByteBuf with the specified capacity.

Specified by:

allocate in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

Parameters:

capacity - the desired capacity of the new buffer.

Returns:

a new I/O capable ByteBuf with the specified capacity.

close

public CompletionStage<Void> close()

Specified by:

close in interface com.ibm.asyncutil.util.AsyncCloseable

Specified by:

close in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

isValid

public boolean isValid()

Specified by:

isValid in interface SimplexTransport<io.netty.buffer.ByteBuf,io.netty.buffer.ByteBuf>

toString

public String toString()

Overrides:

toString in class Object
