The IEvaluator type exposes the following members.
Clears the evaluation, eliminating all data that has been collected up to this point. Since this data is cached as needed, this method can be useful to gather information that is guaranteed to not be out-of-date.
Evaluates this item to determine the dates and times for which it occurs/recurs. This method only evaluates items which occur/recur between fromDate and toDate; therefore, if you require a list of items which occur outside of this range, you must specify a fromDate and toDate which encapsulate the date(s) of interest. This method evaluates using the startDate as the beginning point. For example, for a WEEKLY occurrence, the startDate determines the day of week that this item will recur on.
Note For events with very complex recurrence rules, this method may be a bottleneck during processing time, especially when this method is called for a large number of items, in sequence, or for a very large time span.
