Constructor Detail

ReactiveServerExchangeHandlerback to summary
public ReactiveServerExchangeHandler(final ReactiveRequestProcessor requestProcessor)

Creates a ReactiveServerExchangeHandler.

Parameters
requestProcessor:ReactiveRequestProcessor

the ReactiveRequestProcessor instance to invoke when the request is ready to be handled.

Method Detail

availableback to summary
public int available()

Implements org.apache.hc.core5.http.nio.AsyncDataProducer.available.

Doc from org.apache.hc.core5.http.nio.AsyncDataProducer.available.

Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.

Returns:int

the number of bytes immediately available for output

consumeback to summary
public void consume(final ByteBuffer src) throws IOException

Implements org.apache.hc.core5.http.nio.AsyncDataConsumer.consume.

Doc from org.apache.hc.core5.http.nio.AsyncDataConsumer.consume.

Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.

Parameters
src:ByteBuffer

data source.

public void failed(final Exception cause)

Implements org.apache.hc.core5.http.nio.AsyncDataExchangeHandler.failed.

Doc from org.apache.hc.core5.http.nio.AsyncDataExchangeHandler.failed.

Triggered to signal a failure in data processing.

Parameters
cause:Exception

the cause of the failure.

handleRequestback to summary
public void handleRequest(final HttpRequest request, final EntityDetails entityDetails, final ResponseChannel responseChannel, final HttpContext context) throws HttpException, IOException

Implements org.apache.hc.core5.http.nio.AsyncServerExchangeHandler.handleRequest.

Doc from org.apache.hc.core5.http.nio.AsyncServerExchangeHandler.handleRequest.

Processes the actual HTTP request. The handler can choose to send response messages immediately inside the call or asynchronously at some later point.

Parameters
request:HttpRequest

the actual request.

entityDetails:EntityDetails

the request entity details or null if the request does not enclose an entity.

responseChannel:ResponseChannel

the response channel.

context:HttpContext

the actual execution context.

public void produce(final DataStreamChannel channel) throws IOException

Implements org.apache.hc.core5.http.nio.AsyncDataProducer.produce.

Doc from org.apache.hc.core5.http.nio.AsyncDataProducer.produce.

Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.

Parameters
channel:DataStreamChannel

the data channel capable to accepting more data.
