Method Detail

closeLocalSide

void closeLocalSide(Http2Stream stream,
                  ChannelFuture future)

Closes the local side of the given stream. If this causes the stream to be closed, adds a hook to deactivate the stream and close the channel after the given future completes.

Parameters:

stream - the stream to be half closed.

future - If closing, the future after which to close the channel.

closeRemoteSide

void closeRemoteSide(Http2Stream stream,
                   ChannelFuture future)

Closes the remote side of the given stream. If this causes the stream to be closed, adds a hook to deactivate the stream and close the channel after the given future completes.

Parameters:

stream - the stream to be half closed.

future - If closing, the future after which to close the channel.

closeStream

void closeStream(Http2Stream stream,
               ChannelFuture future)

Closes the given stream and adds a hook to deactivate the stream and close the channel after the given future completes.

Parameters:

stream - the stream to be closed.

future - the future after which to close the channel.

writeRstStream

ChannelFuture writeRstStream(ChannelHandlerContext ctx,
                           int streamId,
                           long errorCode,
                           ChannelPromise promise)

Writes a RST_STREAM frame to the remote endpoint and updates the connection state appropriately.

writeGoAway

ChannelFuture writeGoAway(ChannelHandlerContext ctx,
                        int lastStreamId,
                        long errorCode,
                        ByteBuf debugData,
                        ChannelPromise promise)

Sends a GO_AWAY frame to the remote endpoint and updates the connection state appropriately.

onException

void onException(ChannelHandlerContext ctx,
               Throwable cause)

Processes the given exception.
