public int getFrameBytesGenerated()

Specified by:

getFrameBytesGenerated in class HTTP2Flusher.Entry

generate

protected boolean generate(org.eclipse.jetty.io.ByteBufferPool.Lease lease)
                    throws HpackException

Specified by:

generate in class HTTP2Flusher.Entry

Throws:

HpackException

onFlushed

public long onFlushed(long bytes)

Specified by:

onFlushed in class HTTP2Flusher.Entry

beforeSend

private void beforeSend()

Performs actions just before writing the frame to the network.

Some frame, when sent over the network, causes the receiver to react and send back frames that may be processed by the original sender *before* succeeded() is called.

If the action to perform updates some state, this update may not be seen by the received frames and cause errors.

For example, suppose the action updates the stream window to a larger value; the sender sends the frame; the receiver is now entitled to send back larger data; when the data is received by the original sender, the action may have not been performed yet, causing the larger data to be rejected, when it should have been accepted.

succeeded

public void succeeded()
