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.

    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.
    Set<KappaTerm>
    getSubTerms()
    Processes all the sub-terms
    int
    greaterEqualThan()
    Return The minimum value of this kappa term, such that the caller knows the kappa term is greater or equal the returned value.
    int
    value()
    Return The value of this kappa term or -1 if the kappa-term's evaluate() method returns false.
