    • getValue

      public abstract double getValue(Feature feature)
      Returns the value (as a double) of this part of the formula. It may be the result of a sub-formula, a feature-specific attribute value or just a constant value... Since the value may depend on a feature, we give the feature to the method to get a unified interface...
      Returns:
      value of this part of the formula

    • isFeatureDependent

      public abstract boolean isFeatureDependent()
      Helps to determine, if the value depends on a feature's attribute value.
      Returns:
      true, if the value depends on a feature

    • toString

      public String toString()
