Design Pattern - Behavioral - Chain of Responsibility

Scenario:

Create exclusions for cron scheduler 

Solution:

Behavioral Pattern is used to chain the objects and pass the request along it until an object handles it.

Example: Create exclusions for cron scheduler 

1 2 3 4 5 6 7 8 9 10 11 12

private ICalendar Scheduler(string exclusions) { ICalendar cal = null; var list = exclusions.Split(new[] { ListDelim }, StringSplitOptions.RemoveEmptyEntries); //chain exclusions foreach (var item in list) { cal = new CronCalendar(cal, item); } return cal; }
