Class CATServiceHelper

java.lang.Object
  org.dlese.dpc.schemedit.standards.CATServiceHelper

All Implemented Interfaces:

SuggestionServiceHelper

Direct Known Subclasses:

AsnSuggestionServiceHelper, CommCoreServiceHelper, DleseSuggestionServiceHelper, TeachersDomainServiceHelper

public abstract class CATServiceHelper
extends Object
implements SuggestionServiceHelper

Run-time support for CAT suggestion service, which acts as intermediary between CAT Service client and Form bean/JSP pages.

The CAT service UI involves extraction of several values from the item record being edited for each framework, such as selected keywords, selected graderanges, etc. The functionality to extract these values is delegated to the framework-specific plug-in, which implments CATHelperPlugin.
