Example 3 with WriteBufferByteBased

use of org.apache.plc4x.java.spi.generation.WriteBufferByteBased in project plc4x by apache.

the class Df1Protocol method encode.

@Override
protected void encode(ChannelHandlerContext ctx, DF1Command msg, ByteBuf out) throws Exception {
    // Create a new df1 frame for transmitting the command
    DF1SymbolMessageFrame frame = new DF1SymbolMessageFrame(remoteAddr, localAddr, msg);
    // Serialize the message
    WriteBufferByteBased writeBuffer = new WriteBufferByteBased(frame.getLengthInBytes());
    frame.serialize(writeBuffer);
    byte[] data = writeBuffer.getData();
    // Send the serialized data
    // ctx.writeAndFlush(data);
    out.writeBytes(data);
