Use Attributes in commands

General Development

Hello!
Is it possible to use attributes in a command? Not to read it in a client, only use it as a variable. If yes, how can I do this? How to get the value of an attribute?

Hi,

Let’s consider an example Java Tango server.

The attribute will be normally a field in this case:


@Attribute
private double myDoubleAttr;

//setters and getters

So using that attribute in a command in this case is straightforward:


@Command
public double readMyDoubleAttr(){
  return this.myDoubleAttr;
}

Hope this helps.

I’m not really familiar with Java. Could you please show me an example in C++?

Well, in C++ there is too much boilerplate code. You can easily generate one using Pogo for instance.

The basic idea is that you have a field say myDoubleAttr wich you get/set via read_/write_ methods.

In any other method, which may be a command method, just access the field e.g. this->myDoubleAttr

Hope this helps.
