Method Detail

writeData

ChannelFuture writeData(ChannelHandlerContext ctx,
                        int streamId,
                        ByteBuf data,
                        int padding,
                        boolean endStream,
                        ChannelPromise promise)

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.

promise - the promise for the write.

Returns:

the future for the write.
