Enclosing interface:

Expression
```
public static class Expression.ComparisonExpression
extends Expression.SerialExpression
```
Has exactly two operands, and the operator is one of '==', '!=', '<=', '>', etc

```
    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
