DefaultNHttpClientConnection

@Deprecated
public DefaultNHttpClientConnection(IOSession session,
 HttpResponseFactory responseFactory,
 ByteBufferAllocator allocator,
 HttpParams params)

Deprecated.

(4.3) use DefaultNHttpClientConnection(IOSession, int, int, ByteBufferAllocator, CharsetDecoder, CharsetEncoder, MessageConstraints, ContentLengthStrategy, ContentLengthStrategy, NHttpMessageWriterFactory, NHttpMessageParserFactory)

Creates a new instance of this class given the underlying I/O session.

Parameters:

session - the underlying I/O session.

responseFactory - HTTP response factory.

allocator - byte buffer allocator.

params - HTTP parameters.

 CharsetEncoder charencoder,
 MessageConstraints constraints,
 ContentLengthStrategy incomingContentStrategy,
 ContentLengthStrategy outgoingContentStrategy,
 NHttpMessageWriterFactory<HttpRequest> requestWriterFactory,
 NHttpMessageParserFactory<HttpResponse> responseParserFactory)

Creates new instance DefaultNHttpClientConnection given the underlying I/O session.

Parameters:

session - the underlying I/O session.

buffersize - buffer size. Must be a positive number.

fragmentSizeHint - fragment size hint.

allocator - memory allocator. If null HeapByteBufferAllocator.INSTANCE will be used.

chardecoder - decoder to be used for decoding HTTP protocol elements. If null simple type cast will be used for byte to char conversion.

charencoder - encoder to be used for encoding HTTP protocol elements. If null simple type cast will be used for char to byte conversion.

constraints - Message constraints. If null MessageConstraints.DEFAULT will be used.

incomingContentStrategy - incoming content length strategy. If null LaxContentLengthStrategy.INSTANCE will be used.

outgoingContentStrategy - outgoing content length strategy. If null StrictContentLengthStrategy.INSTANCE will be used.

Method Details

resetInput

public void resetInput()

Description copied from interface: NHttpClientConnection

Resets input state. This method can be used to prematurely terminate processing of the incoming HTTP response.

Specified by:

resetInput in interface NHttpClientConnection

resetOutput

public void resetOutput()

Description copied from interface: NHttpClientConnection

Resets output state. This method can be used to prematurely terminate processing of the outgoing HTTP request.

Specified by:

resetOutput in interface NHttpClientConnection

consumeInput

public void consumeInput(NHttpClientEventHandler handler)

produceOutput

public void produceOutput(NHttpClientEventHandler handler)

submitRequest

public void submitRequest(HttpRequest request)
                   throws IOException,
HttpException

Description copied from interface: NHttpClientConnection

Submits HttpRequest to be sent to the target server.

Specified by:

submitRequest in interface NHttpClientConnection

Parameters:

request - HTTP request

Throws:

IOException - if I/O error occurs while submitting the request

HttpException - if the HTTP request violates the HTTP protocol.

isRequestSubmitted

public boolean isRequestSubmitted()

Description copied from interface: NHttpClientConnection

Returns true if an HTTP request has been submitted to the target server.

Specified by:

isRequestSubmitted in interface NHttpClientConnection

Returns:

true if an HTTP request has been submitted, false otherwise.

consumeInput

public void consumeInput(NHttpClientHandler handler)

Description copied from interface: NHttpClientIOTarget

Specified by:

consumeInput in interface NHttpClientIOTarget

Parameters:

handler - the client protocol handler.

produceOutput

public void produceOutput(NHttpClientHandler handler)

Description copied from interface: NHttpClientIOTarget

Triggered when the connection is ready to produce output.

Specified by:

produceOutput in interface NHttpClientIOTarget

Parameters:

handler - the client protocol handler.
