Method Detail

getMoveToSourceProcess

public Transition getMoveToSourceProcess(SaleProcess p,
                                         SalesPoint sp,
                                         DataBasket dbSource,
                                         Catalog cDest,

                                         TwoTableFormSheet ttfs)

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

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.

dbSource - the source DataBasket.

cDest - the destination Catalog.

ci - the CatalogItem that is selected in the destination.

ttfs - the FormSheet that triggers the process.

getCheckMoveToSourceGate

protected Gate getCheckMoveToSourceGate(SaleProcess p,
                                        SalesPoint sp,
                                        DataBasket dbSource,
                                        Catalog cDest,

                                        TwoTableFormSheet ttfs)

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

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

Override:

Never.

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

Parameters:

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

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

dbSource - the source DataBasket.

cDest - the destination Catalog.

ci - the CatalogItem that is selected in the destination.

ttfs - the FormSheet that triggers the process.

                                CatalogItem ci)
                         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 0.

Parameters:
