Method Details

initalizeContext

public void initalizeContext(HttpContext context,
 Object attachment)

Description copied from interface: NHttpRequestExecutionHandler

Triggered when a new connection has been established and the HTTP context needs to be initialized.

The attachment object is the same object which was passed to the connecting I/O reactor when the connection request was made. The attachment may optionally contain some state information required in order to correctly initalize the HTTP context.

Specified by:

initalizeContext in interface NHttpRequestExecutionHandler

Parameters:

context - the actual HTTP context

attachment - the object passed to the connecting I/O reactor upon the request for a new connection.

finalizeContext

public void finalizeContext(HttpContext context)

Description copied from interface: NHttpRequestExecutionHandler

Triggered when the connection is terminated. This event can be used to release objects stored in the context or perform some other kind of cleanup.

Specified by:

finalizeContext in interface NHttpRequestExecutionHandler

Parameters:

context - the actual HTTP context

submitRequest

public HttpRequest submitRequest(HttpContext context)

Description copied from interface: NHttpRequestExecutionHandler

Triggered when the underlying connection is ready to send a new HTTP request to the target host. This method may return null if the client is not yet ready to send a request. In this case the connection will remain open and can be activated at a later point.

If the request has an entity, the entity must be an instance of ProducingNHttpEntity.

Specified by:

submitRequest in interface NHttpRequestExecutionHandler

Parameters:

context - the actual HTTP context

Returns:

an HTTP request to be sent or null if no request needs to be sent

responseEntity

public ConsumingNHttpEntity responseEntity(HttpResponse response,
 HttpContext context)
                                    throws IOException

Description copied from interface: NHttpRequestExecutionHandler

Triggered when a response is received with an entity. This method should return a ConsumingNHttpEntity that will be used to consume the entity. null is a valid response value, and will indicate that the entity should be silently ignored.

After the entity is fully consumed, NHttpRequestExecutionHandler.handleResponse(HttpResponse, HttpContext) is called to notify a full response & entity are ready to be processed.

Specified by:

responseEntity in interface NHttpRequestExecutionHandler

Parameters:

response - The response containing the existing entity.

context - the actual HTTP context

Returns:

An entity that will asynchronously consume the response's content body.

Throws:

IOException

handleResponse

public void handleResponse(HttpResponse response,
 HttpContext context)
                    throws IOException

Description copied from interface: NHttpRequestExecutionHandler

Triggered when an HTTP response is ready to be processed.

Specified by:

handleResponse in interface NHttpRequestExecutionHandler

Parameters:

response - the HTTP response to be processed

context - the actual HTTP context

Throws:

IOException
