示例1: newConsumer

import org.apache.edgent.function.Function; //導入依賴的package包/類
<T> Consumer<JsonObject> newConsumer(Class<T> datatype, Function<JsonObject,String> addressFn, Function<JsonObject,T> valueFn) {
  PlcConnectionAdapter.checkDatatype(datatype);
  return new Consumer<JsonObject>() {
    private static final long serialVersionUID = 1L;

    @Override
    public void accept(JsonObject jo) {
      PlcConnection connection = null;
      Address address = null;
      try {
        connection = getConnection();
        String addressStr = addressFn.apply(jo);
        address = connection.parseAddress(addressStr);
        T value = valueFn.apply(jo);
        PlcWriter writer = connection.getWriter().get();
        PlcWriteRequest writeReq = newPlcWriteRequest(address, value);
        writer.write(writeReq).get();
      }
      catch (Exception e) {
        logger.error("writing to plc device {} {} failed", connection, address, e);
      }
    }
    
  };
