evalSet
public HashSet<Integer> evalSet(HashMap<String,HashSet<Integer>> hh)
Description copied from interface:Expression.ArithmeticExpression
Evaluates this expression for the given values of the variables involved. Can be used when the arguments can have multiple values.- Specified by:
evalSet
in interfaceExpression.ArithmeticExpression
- Overrides:
evalSet
in classExpression.SerialExpression
- Parameters:
hh
- The hash map that contains for each variable the possible set of its values.- Returns:
- the set of the possible values of the expression, or an empty set if the expression uses a variable whose value is not in h
