Method Summary

fillStock(Stock st, Value v, DataBasket db) The actual algorithm.

Method Detail

fillStock

public Value fillStock(Stock st,
                       Value v,
                       DataBasket db)

The actual algorithm.

The method should add StockItems to st so that the total value of all these items becomes the biggest value that is smaller or equal v. The difference between v and the actual total value of the added StockItems is to be returned.

To avoid dead-locks, this method must not trigger any threads!

Parameters:

st - the Stock to which to add the StockItems.

v - the value to be added to the Stock.

db - the DataBasket relative to which to perform the operation.
