Method Detail

evalSet

public HashSet<Integer> evalSet(HashMap<String,HashSet<Integer>> h)

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

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

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

Specified by:

evalSet2 in interface Expression.ArithmeticExpression

toString

public String toString()

Overrides:

toString in class Object

toSrc

public String toSrc()

Specified by:

toSrc in interface Expression

listAllVars

public HashSet<String> listAllVars()

Specified by:

listAllVars in interface Expression.ArithmeticExpression

map

public Expression map(Expression.Mapper mapper)
               throws RuleParseException

Specified by:

map in interface Expression

Throws:

RuleParseException
