public static interface Expression.ArithmeticExpression extends Expression
An arithmetic expression is composed of variables, constants, and arithmetic operations; parentheses can be used for ordering operations. The value of the expression can be computed for any given set of variable values (unless a division by zero etc happens).

Method Detail

evalSet
HashSet<Integer> evalSet(HashMap<String,HashSet<Integer>> h)
Evaluates this expression for the given values of the variables involved. Can be used when the arguments can have multiple values.- Parameters:
h- 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
-
evalSet2
HashSet<Object> evalSet2(Expression.VarMap2 h)
