Instance Method Details

#add(spec, attrs = {}) ⇒ Object

Assigns a DC spec value object to the given variable for this specset

The attrs hash is expected to defined as follows:
  attrs = {
    specset:  :specset_name,    # if not defined, specset = :default
                                # Spec selectors that contain both the scope and value of the spec
    nom:      { typ:  1.8 },    # typ is an example of the UFlex scope, nom is the spec selector
    min:      { min:  1.7 },    # Users can defined any number of selectors in this fashion
    max:      { max:  1.9 }
  }
