Cannot override non-virtual method 'sys::Component.setToDefault'

[eric_...@yahoo.com]

Hello,

To further my understanding of the Sedona framework, I decided to play around with the pricomp kit. I started out with the "Prioritized" class and threw it in my editor. After messing around with it a good bit and working through tons of compile errors, I got it back to its original state and found another compile error that I just cannot figure out.

It is my understanding based on the documentation I've read, that Prioritized is an extension of sys::Component and "setToDefault" is a virtual method of Component, that can be overridden by a subclass. When I try to invoke setToDefault, I get a "Cannot override non-virtual method 'sys::Component.setToDefault'" compile error.

Can anyone explain what I'm missing here?

Have you declared setToDefault method in subclass with override keyword?

override virtual void setToDefault(Slot slot)
{
...
}

I sure have. This is basically the original source code of the Prioritized class, minus the notes, which I've just simply copy/pasted and cannot get to compile. 

abstract class Prioritized

  extends Component

{

  define int FB_LEVEL  =  17

 @readonly 

  @range=srcLevelStr

  @summary=false property int sourceLevel = FB_LEVEL

  @readonly 

  @unit = Units.nanosecond

  @summary=false property long overrideExpTime = 0L

  define Str srcLevelStr= "in0, emergency, in2, in3, in4, in5, in6, in7, override, in9, in10, in11, in12, in13, in14, in15, in16, fallback"

  

override virtual void setToDefault(Slot slot)

  {

    switch (slot.type.id)

    {

      case Type.boolId:   setBool(slot, null); break

      case Type.byteId:

      case Type.shortId:

      case Type.intId:    setInt(slot, Sys.minInt); break

      case Type.longId:   setLong(slot, Sys.minLong); break

      case Type.floatId:  setFloat(slot, null); break

      case Type.doubleId: setDouble(slot, null); break

      case Type.bufId:    getBuf(slot).clear(); break

Hi Eric,

OK. This code compiles without a problem.
Could you describe in details, what doesn't compile?
Complete source code or minimal example of your problem would be perfect.

By the way Prioritized class is abstract and therefore can not be
instantiated. Maybe this is your problem?

Thank you for you're response!

Maybe it's my compiler? (EasyIO CPT)

I was taking the source code for the "pricomp" kit and was going to play around and add a few simple things to the sub classes (Prioritized Bool, Numeric, etc.), then compile it. Prioritize is the base class for everything in the kit, so I started with that, but that's the class I can't get to compile. It's the exact same code I posted previously, which you said compiled for you.

I understand that it can't be instantiated, since it's abstract, but I don't believe it has anything to do with that.

Ok, so I just tried to load the "pricomp" kit directly into a controller and it failed to load the kit and gave a similar error as to when I try to compile it, so it's something with the source.

The error is " unknown override 'pricomp::Prioritized.setToDefault' "

I pulled the kit directly from 1.2.28 build from the website.

Pricomp has dependency to sys  1.2.2+.  Are you sure you are compiling against that?

easyIO uses sedona 1.0 and not 1.2, this is your problem.
