Field Detail

m_dbBasket

protected DataBasket m_dbBasket

The DataBasket being modelled.

m_dbcCondition

protected DataBasketCondition m_dbcCondition

The condition specifying the items to be displayed.

m_dbegGrouper

protected DataBasketEntryGrouper m_dbegGrouper

A strategy that will group individual DataBasketEntries together for display. If null, no grouping will occur.

m_cmpComparator

Constructor Detail

DataBasketTableModel

public DataBasketTableModel(DataBasket db,
                            DataBasketCondition dbc,
                            DataBasketEntryGrouper dbeg,
                            Comparator cmp,
                            TableEntryDescriptor ted)

Create a new DataBasketTableModel.

Parameters:

db - the DataBasket to be modellled.

dbc - a condition specifying the DataBasketEntries to be part of the model.

dbeg - a strategy that will group individual DataBasketEntries together for display. If null, no grouping will occur.

cmp - a Comparator defining the sort order of the records. If null, records are ordered according to the main key of the entries first and of the secondary key second.

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