com.clra.web
Class EnrollmentSet  

java.lang.Object
  com.clra.web.EnrollmentSet

All Implemented Interfaces:

IEventList

---

public class EnrollmentSet

extends java.lang.Object

implements IEventList

A JSP bean that provides ordered lists of EnrollmentViews. This class is a thin wrapper around calls to RowingUtils. In the future, it might add further value by caching and sorting views on the client side.

FIXME: this class is basically a list, not a set. A set hides duplicates, whereas a list does not. Rename this class.

In the current implementation, a list is created on the fly whenever a JSP is displayed, and the list is tossed after the page is written. For lists of 60 or so items, a page will update in 2 - 3 seconds when the app and web servers are lightly loaded. This is adequate performance, since most lists will be restricted by month, and therefore will contain roughly 30 items.
