Method Details

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 interface Expression.ArithmeticExpression

Overrides:

evalSet in class Expression.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

evalSet2

public HashSet<Object> evalSet2(Expression.VarMap2 hh)

Specified by:

evalSet2 in interface Expression.ArithmeticExpression

Overrides:

evalSet2 in class Expression.SerialExpression

map

public Expression map(Expression.Mapper mapper)
               throws RuleParseException

Applies the mapper to each component

Throws:

RuleParseException
