      context.arch.discoverer.dataModel.DiscovererDataModel

public class DiscovererDataModel

extends AbstractDataModel

This class stores the ComponentDescriptions of the CTK object that register to the discoverer. It stores the complete ComponentDescription in a Hashtable and maintain a set of IndexTableIF that allows to search more quickly for particular CTK objects. They are index on each of the description element.
