Class SubjectComparatorHelper

java.lang.Object

edu.internet2.middleware.grouper.ui.SubjectComparatorHelper

All Implemented Interfaces:

GrouperComparatorHelper, Serializable

public class SubjectComparatorHelper
extends Object
implements GrouperComparatorHelper

Implementation of ComparatorHelper used to sort Subjects. Can also sort SubjectAsMaps, Members, Memberships, MembershipAsMaps which can all be shown as Subjects. The context affects sorting thus:

• If it starts 'search:', then context is changed to 'search'
• Otherwise '<type>.sort.<context>', '<type>.sort.<default>', 'subject.sort.<context>', 'subject.sort.<sourceId>.<context>','subject.sort.<sourceid>', 'subject.sort.default', 'subject.display.<sourceId>' and 'subject.display.default' are looked up until a value is found

If the sort field contains spaces, the field is 'split' and each sub part is assumed to be separate attribute to sort on.

In order to sort subjects with the same type together, you can configure, in media.properties a pre-sort string e.g.

• subject.pre-sort.g\:gsa=a
• subject.pre-sort.qsuob=b

will sort all groups before QuickStart subjects.
