HttpConnection

public HttpConnection(HttpConfiguration config,
                      Connector connector,
                      EndPoint endPoint)

Method Detail

getCurrentConnection

public static HttpConnection getCurrentConnection()

Get the current connection that this thread is dispatched to. Note that a thread may be processing a request asynchronously and thus not be dispatched to the connection.

Returns:

the current HttpConnection or null

setCurrentConnection

protected static HttpConnection setCurrentConnection(HttpConnection connection)

getHttpConfiguration

public HttpConfiguration getHttpConfiguration()

newHttpGenerator

protected HttpGenerator newHttpGenerator()

newHttpChannel

protected org.eclipse.jetty.server.HttpChannelOverHttp newHttpChannel()

newHttpParser

protected HttpParser newHttpParser()

newRequestHandler

protected HttpParser.RequestHandler newRequestHandler()

getServer

public Server getServer()

getConnector

public Connector getConnector()

getHttpChannel

public HttpChannel getHttpChannel()

getParser

public HttpParser getParser()

getGenerator

public HttpGenerator getGenerator()

isOptimizedForDirectBuffers

public boolean isOptimizedForDirectBuffers()

Description copied from interface: HttpTransport

Is the underlying transport optimized for DirectBuffer usage

Specified by:

isOptimizedForDirectBuffers in interface HttpTransport

Returns:

True if direct buffers can be used optimally.

getMessagesIn

public int getMessagesIn()

Specified by:

getMessagesIn in interface Connection

Overrides:

getMessagesIn in class AbstractConnection

getMessagesOut

public int getMessagesOut()

Specified by:

getMessagesOut in interface Connection

Overrides:

getMessagesOut in class AbstractConnection

onUpgradeFrom

public ByteBuffer onUpgradeFrom()

Description copied from interface: Connection.UpgradeFrom

Take the input buffer from the connection on upgrade.

This method is used to take any unconsumed input from a connection during an upgrade.

Specified by:

onUpgradeFrom in interface Connection.UpgradeFrom

Returns:

A buffer of unconsumed input. The caller must return the buffer to the bufferpool when consumed and this connection must not.

getRequestBuffer

public ByteBuffer getRequestBuffer()

isRequestBufferEmpty

public boolean isRequestBufferEmpty()

onFillable

public void onFillable()

Description copied from class: AbstractConnection

Callback method invoked when the endpoint is ready to be read.

Specified by:

onFillable in class AbstractConnection

See Also:

AbstractConnection.fillInterested()

fillAndParseForContent

protected boolean fillAndParseForContent()

Fill and parse data looking for content

Returns:

true if an HttpParser.RequestHandler method was called and it returned true;

onCompleted

public void onCompleted()

Specified by:

onCompleted in interface HttpTransport

onFillInterestedFailed

protected void onFillInterestedFailed(Throwable cause)

Description copied from class: AbstractConnection

Callback method invoked when the endpoint failed to be ready to be read.

Overrides:

onFillInterestedFailed in class AbstractConnection

Parameters:

cause - the exception that caused the failure

onOpen

public void onOpen()

Specified by:

onOpen in interface Connection

Overrides:

onOpen in class AbstractConnection

onClose

public void onClose()

Description copied from interface: Connection

Callback method invoked when this Connection is closed.

Creators of the connection implementation are responsible for calling this method.

Specified by:

onClose in interface Connection

Overrides:

onClose in class AbstractConnection

run

public void run()

Specified by:

run in interface Runnable

send

public void send(MetaData.Response info,
                 boolean head,
                 ByteBuffer content,
                 boolean lastContent,
                 Callback callback)

Specified by:

send in interface HttpTransport

abort

public void abort(Throwable failure)

Description copied from interface: HttpTransport

Aborts this transport.

This method should terminate the transport in a way that can indicate an abnormal response to the client, for example by abruptly close the connection.

This method is called when an error response needs to be sent, but the response is already committed, or when a write failure is detected.

Specified by:

abort in interface HttpTransport

Parameters:

failure - the failure that caused the abort.

isPushSupported

public boolean isPushSupported()

Specified by:

isPushSupported in interface HttpTransport

push

public void push(MetaData.Request request)

Specified by:

push in interface HttpTransport

See Also:

HttpTransport.push(org.eclipse.jetty.http.MetaData.Request)

asyncReadFillInterested

public void asyncReadFillInterested()

blockingReadFillInterested

public void blockingReadFillInterested()

toString

public String toString()

Overrides:

toString in class AbstractConnection
