Examples of heart.alsvfd.Value.subset()

heart.alsvfd.Value.subset()
A method that should be used to check is the value is a subset of value given as a parameter. @param v - a value to be processed. Both values should be a sets, or ranges. @param t - a type with respect to witch the operator should work. If null, no domain is taken into consideration while evaluating. @return true if the value is subset of v, false otherwise @throws UnsupportedOperationException in cases when operator is not applicable to the values being parameters of the operation. @throws NotInTheDomainException


  @Override
  public UncertainTrue evaluateUncertainSubset(Attribute at, Value v, WorkingMemory wm)
      throws UnsupportedOperationException, NotInTheDomainException {
    Value attributeValue = wm.getAttributeValue(at);
    boolean logicalValue = attributeValue.subset(v, at.getType());
    
    return (logicalValue ? new UncertainTrue(getMaxCertainty()): new UncertainTrue(getMinCertainty()));
