java.lang.Object
  org.apache.http.nio.protocol.BufferingHttpServiceHandler

All Implemented Interfaces:

NHttpServiceHandler

Deprecated. (4.2) use HttpAsyncService

@Deprecated
@Contract(threading=IMMUTABLE_CONDITIONAL)
public class BufferingHttpServiceHandler
extends Object
implements NHttpServiceHandler

Service protocol handler implementations that provide compatibility with the blocking I/O by storing the full content of HTTP messages in memory. The HttpRequestHandler.handle(HttpRequest, HttpResponse, HttpContext) method will fire only when the entire message content has been read into an in-memory buffer. Please note that request processing take place the main I/O thread and therefore individual HTTP request handlers should not block indefinitely.

When using this protocol handler HttpEntity's content can be generated / consumed using standard InputStream/ OutputStream classes.

IMPORTANT: This protocol handler should be used only when dealing with HTTP messages that are known to be limited in length.

Since:

4.0

public BufferingHttpServiceHandler(HttpProcessor httpProcessor,
                                   HttpResponseFactory responseFactory,
                                   ConnectionReuseStrategy connStrategy,

                                   HttpParams params)

Deprecated.

Method Detail

setEventListener

public void setEventListener(EventListener eventListener)

Deprecated.

setExpectationVerifier

public void setExpectationVerifier(HttpExpectationVerifier expectationVerifier)

Deprecated.

setHandlerResolver

public void setHandlerResolver(HttpRequestHandlerResolver handlerResolver)

Deprecated.

connected

public void connected(NHttpServerConnection conn)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when a new incoming connection is created.

Specified by:

connected in interface NHttpServiceHandler

Parameters:

conn - new incoming connection HTTP connection.

closed

public void closed(NHttpServerConnection conn)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when the connection is closed.

Specified by:

closed in interface NHttpServiceHandler

Parameters:

conn - closed HTTP connection.

requestReceived

public void requestReceived(NHttpServerConnection conn)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when a new HTTP request is received. The connection passed as a parameter to this method is guaranteed to return a valid HTTP request object.

If the request received encloses a request entity this method will be followed a series of NHttpServiceHandler.inputReady(NHttpServerConnection, ContentDecoder) calls to transfer the request content.

Specified by:

requestReceived in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that contains a new HTTP request

See Also:

NHttpServerConnection

inputReady

public void inputReady(NHttpServerConnection conn,
                       ContentDecoder decoder)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when the underlying channel is ready for reading a new portion of the request entity through the corresponding content decoder.

If the content consumer is unable to process the incoming content, input event notifications can be temporarily suspended using IOControl interface.

Specified by:

inputReady in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that can produce a new portion of the incoming request content.

decoder - The content decoder to use to read content.

See Also:

NHttpServerConnection, ContentDecoder, IOControl

responseReady

public void responseReady(NHttpServerConnection conn)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when the connection is ready to accept a new HTTP response. The protocol handler does not have to submit a response if it is not ready.

Specified by:

responseReady in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that contains an HTTP response

See Also:

NHttpServerConnection

outputReady

public void outputReady(NHttpServerConnection conn,
                        ContentEncoder encoder)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when the underlying channel is ready for writing a next portion of the response entity through the corresponding content encoder.

If the content producer is unable to generate the outgoing content, output event notifications can be temporarily suspended using IOControl interface.

Specified by:

outputReady in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that can accommodate a new portion of the outgoing response content.

encoder - The content encoder to use to write content.

See Also:

NHttpServerConnection, ContentEncoder, IOControl

exception

public void exception(NHttpServerConnection conn,
                      HttpException httpex)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when an HTTP protocol violation occurs while receiving an HTTP request.

Specified by:

exception in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that caused an HTTP protocol violation

httpex - HTTP protocol violation exception

exception

public void exception(NHttpServerConnection conn,
                      IOException ioex)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when an I/O error occurs while reading from or writing to the underlying channel.

Specified by:

exception in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that caused an I/O error

ioex - I/O exception

timeout

public void timeout(NHttpServerConnection conn)

Deprecated.

Description copied from interface: NHttpServiceHandler

Triggered when no input is detected on this connection over the maximum period of inactivity.

Specified by:

timeout in interface NHttpServiceHandler

Parameters:

conn - HTTP connection that caused timeout condition.
