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

for a more general way to access the HttpConnection

setCurrentConnection

protected static HttpConnection setCurrentConnection(HttpConnection connection)

getHttpConfiguration

public HttpConfiguration getHttpConfiguration()

newHttpGenerator

protected HttpGenerator newHttpGenerator()

newHttpInput

protected HttpInput<ByteBuffer> newHttpInput()

newHttpChannel

protected HttpConnection.HttpChannelOverHttp newHttpChannel(HttpInput<ByteBuffer> httpInput)

newHttpParser

protected HttpParser newHttpParser()

newRequestHandler

protected HttpParser.RequestHandler<ByteBuffer> newRequestHandler()

getServer

public Server getServer()

getConnector

public Connector getConnector()

getHttpChannel

public HttpChannel<?> getHttpChannel()

getParser

public HttpParser getParser()

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

getRequestBuffer

public ByteBuffer getRequestBuffer()

onFillable

public void onFillable()

Parses and handles HTTP messages.

This method is called when this Connection is ready to read bytes from the EndPoint. However, it can also be called if there is unconsumed data in the _requestBuffer, as a result of resuming a suspended request when there is a pipelined request already read into the buffer.

This method fills bytes and parses them until either: EOF is filled; 0 bytes are filled; the HttpChannel finishes handling; or the connection has changed.

Specified by:

onFillable in class AbstractConnection

See Also:

AbstractConnection.fillInterested()

parseContent

protected void parseContent()
                     throws IOException

Fill and parse data looking for content

Throws:

IOException

completed

public void completed()

Specified by:

completed 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()

Description copied from interface: Connection

Callback method invoked when this Connection is opened.

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

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(HttpGenerator.ResponseInfo info,
        ByteBuffer content,
        boolean lastContent,
        Callback callback)

Specified by:

send in interface HttpTransport

send

public void send(ByteBuffer content,
        boolean lastContent,
        Callback callback)

Specified by:

send in interface HttpTransport

abort

public void abort()

Description copied from interface: HttpTransport

Abort transport. This is called when an error response needs to be sent, but the response is already committed. Abort to should terminate the transport in a way that can indicate abnormal response to the client.

Specified by:

abort in interface HttpTransport
