Interface KappaTerm

All Known Implementing Classes:
KappaMin, KappaSum, KappaValue
public interface KappaTerm
This interface defines a kappa term, that can be evaluated, it can return its value, which is -1 as long as the kappa-term cannot be evaluated and it can return a value for that we know that the kappa-term value is greatar or equal to that value.

  • Method Details

    • evaluate

      boolean evaluate()
      Tries to evaluate the kappa term, if the evaluation is successful then the next call of value returns the evaluated value.
      Returns:
      True if the evaluation is sucessful, false otherwise

    • value

      int value()
      Returns:
      The value of this kappa term or -1 if the kappa-term's evaluate() method returns false.

    • greaterEqualThan

      int greaterEqualThan()
      Returns:
      The minimum value of this kappa term, such that the caller knows the kappa term is greater or equal the returned value.

    • getSubTerms

      Set<KappaTerm> getSubTerms()
      Processes all the sub-terms
      Returns:
      A set containing all the sub-terms of the kappa term
