public AlternativeExpression(Expression condition,
                             IRuleBlock ifPart,
                             IRuleBlock elsePart)
                      throws VilException

Creates an alternative expression.

Parameters:

condition - the condition to be evaluated

ifPart - the if-part to be executed if the alternative is true
