Class observe::Windowed

Windowed observable.

This creates a "windowed" version of any observable such that the current state of the contained observable always reflects the last window_size values recorded. This is implemented by keeping track of the recorded values in the queue and removing them when the window_size is exceeded.

Note

The window_size is implemented as a weight; if all your recorded values have a weight of 1, this translates to window_size observables being tracked; if they differ it can be more or less, accordingly.

render()

render the object in structured form

Return a structured representation of the object. This is intended for output purposes. For instance, the solution your solver finds should have a render method which allows it to be returned as part of the result. Example:

{c++}
 MySolution : public Component {
  public:
   // Represent the internal bool vector as +-1 output.
   utils::Structure render() const override {
     utils::Structure rendered;
     for (bool item : solution_) rendered.push_back(item ? 1 : -1);
     return rendered;
   }

  private:
   std::vector<bool> solution_;
 }

 MySolution solution;
 std::cout << solution.render().to_string() << std::endl;
