Method Detail

createFrameHeaderImpl

protected SendFrameHeader createFrameHeaderImpl()

Specified by:

createFrameHeaderImpl in class Http2StreamSinkChannel

flush

public boolean flush()
              throws IOException

Description copied from interface: SuspendableWriteChannel

Flush any waiting partial send or write. If there is no data to flush, or if the flush completed successfully, this method will return true. If there is data to flush which cannot be immediately written, this method will return false. If this method returns true after SuspendableWriteChannel.shutdownWrites() was called on this channel, the write listener will no longer be invoked on this channel. If this is case and additionally this is a write-only channel or the read side was previously shut down, then the channel will automatically be closed.

Specified by:

flush in interface SuspendableWriteChannel

Overrides:

flush in class AbstractFramedStreamSinkChannel<Http2Channel,AbstractHttp2StreamSourceChannel,AbstractHttp2StreamSinkChannel>

Returns:

true if the message was flushed, or false if the result would block

Throws:

IOException - if an I/O error occurs

writeBeforeHeaderBlock

protected void writeBeforeHeaderBlock(ByteBuffer buffer)

isFlushRequiredOnEmptyBuffer

protected boolean isFlushRequiredOnEmptyBuffer()

Overrides:

isFlushRequiredOnEmptyBuffer in class AbstractFramedStreamSinkChannel<Http2Channel,AbstractHttp2StreamSourceChannel,AbstractHttp2StreamSinkChannel>

getHeaders

public HeaderMap getHeaders()

handleFlushComplete

protected void handleFlushComplete(boolean finalFrame)

Overrides:

handleFlushComplete in class Http2StreamSinkChannel

channelForciblyClosed

protected void channelForciblyClosed()
                              throws IOException

Description copied from class: AbstractFramedStreamSinkChannel

Called when a channel has been forcibly closed, and data (frames) have already been written. The action this should take is protocol dependent, e.g. for SPDY a RST_STREAM should be sent, for websockets the channel should be closed. By default this will just close the underlying channel

Overrides:

channelForciblyClosed in class Http2StreamSinkChannel

Throws:

IOException

getCompletionListener

public ChannelListener<Http2DataStreamSinkChannel> getCompletionListener()

setCompletionListener

public void setCompletionListener(ChannelListener<Http2DataStreamSinkChannel> completionListener)
