Method Details

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

send

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

Description copied from interface: HttpTransport

Asynchronous call to send a response (or part) over the transport

Specified by:

send in interface HttpTransport

Parameters:

info - The header info to send, or null if just sending more data. The first call to send for a response must have a non null info.

head - True if the response if for a HEAD request (and the data should not be sent).

content - A buffer of content to be sent.

lastContent - True if the content is the last content for the current response.

callback - The Callback instance that success or failure of the send is notified on

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. If abort is called, HttpTransport.onCompleted() is not called

Specified by:

abort in interface HttpTransport

Parameters:

failure - the failure that caused the abort.

isPushSupported

public boolean isPushSupported()

Specified by:

isPushSupported in interface HttpTransport

Returns:

true if responses can be pushed over this transport

push

public void push(MetaData.Request request)

Specified by:

push in interface HttpTransport

Parameters:

request - A request to use as the basis for generating a pushed response.

blockingReadFillInterested

public void blockingReadFillInterested()

blockingReadFailure

public void blockingReadFailure(Throwable e)

Overrides:

getBytesIn in class AbstractConnection

getBytesOut

public long getBytesOut()

Specified by:

getBytesOut in interface Connection

Overrides:

getBytesOut in class AbstractConnection

toConnectionString

public String toConnectionString()

Overrides:
