Constructor Detail

StoringStockTableModel

public StoringStockTableModel(Stock st,
                              DataBasket db,
                              Comparator cmp,
                              TableEntryDescriptor ted)

Create a new StoringStockTableModel.

Parameters:

st - the Stock to be modelled.

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 StockItems.

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