      Modifier and Type Method Description
      boolean evaluate()
      Tries to evaluate the kappa term, if the evaluation is successful then the next call of value returns the evaluated value.
      java.util.Set<KappaTerm> getSubTerms()
      Processes all the sub-terms
      int greaterEqualThan()  
      java.lang.String toString()  
      int value()
      The neutral element is zero, that means if the sum contains no elements this method returns zero
