Modifier and Type	Method	Description

Method Detail

writeData

io.netty5.util.concurrent.Future<Void> writeData(io.netty5.channel.ChannelHandlerContext ctx,
                                                 int streamId,
                                                 io.netty5.buffer.Buffer data,
                                                 int padding,
                                                 boolean endStream)

Writes a DATA frame to the remote endpoint. This will result in one or more frames being written to the context.

Parameters:

ctx - the context to use for writing.

streamId - the stream for which to send the frame.

data - the payload of the frame. This will be released by this method.

padding - additional bytes that should be added to obscure the true content size. Must be between 0 and 256 (inclusive). A 1 byte padding is encoded as just the pad length field with value 0. A 256 byte padding is encoded as the pad length field with value 255 and 255 padding bytes appended to the end of the frame.

endStream - indicates if this is the last frame to be sent for the stream.

Returns:

the future for the write.
