 boolean multiplexed)

Method Details

getHttpDestination

public HttpDestination getHttpDestination()

getFlusher

protected Flusher getFlusher()

send

public void send(Request request,
 Response.CompleteListener listener)

Description copied from interface: Connection

Sends a request with an associated response listener.

Request.send(Response.CompleteListener) will eventually call this method to send the request. It is exposed to allow applications to send requests via unpooled connections.

Specified by:

send in interface Connection

Parameters:

request - the request to send

listener - the response listener

send

protected SendFailure send(HttpExchange exchange)

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

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()

reacquireNetworkBuffer

private void reacquireNetworkBuffer()

newNetworkBuffer

private RetainableByteBuffer newNetworkBuffer()

releaseNetworkBuffer

private void releaseNetworkBuffer()

process

void process()

parse

private boolean parse(ByteBuffer buffer)

shutdown

private void shutdown()

onIdleExpired

public boolean onIdleExpired()

Description copied from interface: Connection

Callback method invoked upon an idle timeout event.

Implementations of this method may return true to indicate that the idle timeout handling should proceed normally, typically failing the EndPoint and causing it to be closed.

When false is returned, the handling of the idle timeout event is halted immediately and the EndPoint left in the state it was before the idle timeout event.

Specified by:

onIdleExpired in interface Connection

Overrides:

onIdleExpired in class AbstractConnection

Returns:

true to let the EndPoint handle the idle timeout, false to tell the EndPoint to halt the handling of the idle timeout.

release

protected void release(HttpChannelOverFCGI channel)

close

public void close()

Description copied from interface: Connection

Performs a logical close of this connection.

For simple connections, this may just mean to delegate the close to the associated EndPoint but, for example, SSL connections should write the SSL close message before closing the associated EndPoint.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface Connection

Specified by:

close in interface Connection

Overrides:

close in class AbstractConnection

close

protected void close(Throwable failure)

isClosed

public boolean isClosed()

Specified by:

isClosed in interface Connection

Returns:

whether this connection has been closed

See Also:

• Connection.close()

setAttachment

public void setAttachment(Object obj)

Description copied from interface: Attachable

Attaches the given object to this stream for later retrieval.

Specified by:

setAttachment in interface Attachable

Parameters:

obj - the object to attach to this instance

getAttachment

public Object getAttachment()

Specified by:

getAttachment in interface Attachable

Returns:

the object attached to this instance

See Also:

• Attachable.setAttachment(Object)

closeByHTTP

protected boolean closeByHTTP(HttpFields fields)

abort

protected void abort(Throwable failure)

failAndClose

private void failAndClose(Throwable failure)

acquireRequest

private int acquireRequest()

releaseRequest

private void releaseRequest(int request)

acquireHttpChannel

protected HttpChannelOverFCGI acquireHttpChannel(int id,
 Request request)

newHttpChannel

protected HttpChannelOverFCGI newHttpChannel(Request request)

toConnectionString

public String toConnectionString()

Overrides:

toConnectionString in class AbstractConnection
