Method Detail

getMoveToDestProcess

public Transition getMoveToDestProcess(SaleProcess p,
                                       SalesPoint sp,
                                       Catalog cSource,

                                       TwoTableFormSheet ttfs)

Get the sub-process that will move items from the source to the destination.

Override:

Never.

Parameters:

p - the process into which the sub-process wil be embedded.

sp - the SalesPoint, if any, at which the FormSheet is being displayed.

cSource - the source Catalog.

dbDest - the destination DataBasket.

ci - the CatalogItem that is selected in the source.

ttfs - the FormSheet that triggers the process.

getCheckMoveToDestGate

protected Gate getCheckMoveToDestGate(SaleProcess p,
                                      SalesPoint sp,
                                      Catalog cSource,

                                      TwoTableFormSheet ttfs)

Get the first gate of the sub-process that will move items from the source to the destination.

This Gate will check whether the move is allowable, and if so, will trigger a Transition that performs it.

Override:

Never.

Instead, override checkMoveToDest(sale.SaleProcess, sale.SalesPoint, data.Catalog, data.DataBasket, data.CatalogItem) and/or moveToDest(sale.SaleProcess, sale.SalesPoint, data.Catalog, data.DataBasket, data.CatalogItem).

Parameters:

sp - the SalesPoint, if any, at which the FormSheet is being displayed.

cSource - the source Catalog.

dbDest - the destination DataBasket.

ci - the CatalogItem that is selected in the source.

ttfs - the FormSheet that triggers the process.

                       throws InterruptedException

Check whether the indicated move is allowable. If so, return 0, otherwise return a non-zero error value that can be passed on to FormSheetStrategy.error(sale.SaleProcess, int). You can assume that you are at a Gate.

Override:

Sometimes.

The default implementation returns ProcessErrorCodes.NOT_ENOUGH_ELEMENTS_ERROR if the destination DataBasket contains no entry that describes the given CatalogItem.

p - the process into which the sub-process wil be embedded.

sp - the SalesPoint, if any, at which the FormSheet is being displayed.

cSource - the source Catalog.

dbDest - the destination DataBasket.
