Constructor Detail

CatalogTableModel

public CatalogTableModel(Catalog c,
                         DataBasket db,
                         Comparator cmp,
                         TableEntryDescriptor ted)

Create a new CatalogTableModel.

Parameters:

c - the Catalog to be modelled. May be filtered.

db - the DataBasket to be used to determine visibility.

cmp - a Comparator defining the sort order of the records. If null, records are ordered according to the natural ordering of the CatalogItems.

ted - a TableEntryDescriptor that can split individual CatalogItems into a table's cells.
