Class BufferingHttpClientHandler

java.lang.Object
  extended by org.apache.http.nio.protocol.BufferingHttpClientHandler
All Implemented Interfaces:
NHttpClientHandler

Deprecated. (4.2) use HttpAsyncRequestExecutor and HttpAsyncRequester

@Deprecated
@Immutable
public class BufferingHttpClientHandler
extends Object
implements NHttpClientHandler

Client protocol handler implementation that provides compatibility with the blocking I/O by storing the full content of HTTP messages in memory. The HttpRequestExecutionHandler.handleResponse(HttpResponse, HttpContext) method will fire only when the entire message content has been read into a in-memory buffer. Please note that request execution / response processing take place the main I/O thread and therefore HttpRequestExecutionHandler methods 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

Method Detail

setEventListener

public void setEventListener(EventListener eventListener)
Deprecated. 

connected

public void connected(NHttpClientConnection conn,
                      Object attachment)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when a new outgoing connection is created.

Specified by:
connected in interface NHttpClientHandler
Parameters:
conn - new outgoing HTTP connection.
attachment - an object that was attached to the session request

closed

public void closed(NHttpClientConnection conn)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when the connection is closed.

Specified by:
closed in interface NHttpClientHandler
Parameters:
conn - closed HTTP connection.

requestReady

public void requestReady(NHttpClientConnection conn)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when the connection is ready to accept a new HTTP request. The protocol handler does not have to submit a request if it is not ready.

Specified by:
requestReady in interface NHttpClientHandler
Parameters:
conn - HTTP connection that is ready to accept a new HTTP request.
See Also:
NHttpClientConnection

inputReady

public void inputReady(NHttpClientConnection conn,
                       ContentDecoder decoder)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when the underlying channel is ready for reading a new portion of the response 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 NHttpClientHandler
Parameters:
conn - HTTP connection that can produce a new portion of the incoming response content.
decoder - The content decoder to use to read content.
See Also:
NHttpClientConnection, ContentDecoder, IOControl

outputReady

public void outputReady(NHttpClientConnection conn,
                        ContentEncoder encoder)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when the underlying channel is ready for writing a next portion of the request 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 NHttpClientHandler
Parameters:
conn - HTTP connection that can accommodate a new portion of the outgoing request content.
encoder - The content encoder to use to write content.
See Also:
NHttpClientConnection, ContentEncoder, IOControl

responseReceived

public void responseReceived(NHttpClientConnection conn)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when an HTTP response is received. The connection passed as a parameter to this method is guaranteed to return a valid HTTP response object.

If the response received encloses a response entity this method will be followed by a series of NHttpClientHandler.inputReady(NHttpClientConnection, ContentDecoder) calls to transfer the response content.

Specified by:
responseReceived in interface NHttpClientHandler
Parameters:
conn - HTTP connection that contains an HTTP response
See Also:
NHttpClientConnection

exception

public void exception(NHttpClientConnection conn,
                      HttpException httpex)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when an HTTP protocol violation occurs while receiving an HTTP response.

Specified by:
exception in interface NHttpClientHandler
Parameters:
conn - HTTP connection that caused an HTTP protocol violation
httpex - HTTP protocol violation exception

exception

public void exception(NHttpClientConnection conn,
                      IOException ioex)
Deprecated. 
Description copied from interface: NHttpClientHandler
Triggered when an I/O error occurs while reading from or writing to the underlying channel.

Specified by:
exception in interface NHttpClientHandler
Parameters:
conn - HTTP connection that caused an I/O error
ioex - I/O exception

timeout

public void timeout(NHttpClientConnection conn)
Deprecated.

Specified by:
timeout in interface NHttpClientHandler
Parameters:
conn - HTTP connection that caused timeout condition.
