All Implemented Interfaces:

Serializable, ProcessErrorCodes

public abstract class AbstractAddCatalogItemStrategy
extends EditButtonStrategy

A strategy that can be attached to the "Add" button of a SingleTableFormSheet that displays a Catalog's contents.

This strategy is abstract since the creation of the CatalogItem is application specific. It must be defined by overriding createCatalogItem(java.lang.String).

Since:

v2.0

Create a new AbstractAddCatalogItemStrategy.

Method Detail

getEditProcess

public Transition getEditProcess(SingleTableFormSheet stfs,
                                 SaleProcess p,
                                 SalesPoint sp)

Description copied from class: EditButtonStrategy

Get the first transition of the process that will perform the editing. The process can have any number of Gates and Transitions and display any number of Form- and MenuSheets. Normally, the sub-process should end at the gate at which the SingleTableFormSheet is being displayed, which can be obtained by SingleTableFormSheet.getGate().

Specified by:

getEditProcess in class EditButtonStrategy

Parameters:

stfs - the SingleTableFormSheet that triggers the sub-process.

p - the process into which the sub-process will be implanted.

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

Override:

Never

getCreateCIGate

protected Gate getCreateCIGate(SingleTableFormSheet stfs)

Get the first Gate in the sub-process. This Gate asks the user for the key of the new item, creates it in a new Transition and after editing the new item adds it to the Catalog.

Parameters:

stfs - the FormSheet that triggered the sub-process.

Override:

Never Instead, override getNewKey(data.stdforms.SingleTableFormSheet, sale.SaleProcess), createCatalogItem(java.lang.String), getEditCIGate(data.CatalogItem, data.stdforms.SingleTableFormSheet, sale.Transition) and/or addToCatalog(sale.SaleProcess, data.CatalogItem).

getNewKey

protected String getNewKey(SingleTableFormSheet stfs,
                           SaleProcess p)
                    throws InterruptedException

Get the key of the new item. Can assume that at a Gate.

Parameters:

stfs - the FormSheet that triggered the sub-process.

p - the process into which the sub-process was embedded.

Throws:

InterruptedException

Override:

Sometimes The default implementation pops up a FormSheet where the user can enter a new key.

createCatalogItem

protected abstract CatalogItem createCatalogItem(String sKey)

Create a new CatalogItem of the given key.

Parameters:

sKey - the key for which to create a new CatalogItem.

Returns:

the new CatalogItem.

Override:

Always The contents of this method is application specific.

getEditCIGate

protected Gate getEditCIGate(CatalogItem ci,
                             SingleTableFormSheet stfs,
                             Transition tOk)

Get a Gate at which a newly created CatalogItem can be edited by the user.

Parameters:

ci - the CatalogItem to be edited.

stfs - the FormSheet that triggered the sub-process. A transition to this FormSheet's gate must be leaving the Gate if the user cancels the operation.

tOk - the Transition that must be leaving the Gate if the user finished editing and did not cancel the operation or enter invalid data.

Override:

Sometimes The default implementation simply continues with tOk.

addToCatalog

protected void addToCatalog(SaleProcess p,
                            CatalogItem ci)

Add the specified CatalogItem to the Catalog.

Any error condition should be passed on to FormSheetStrategy.error(sale.SaleProcess, int) in FormSheetStrategy.

Parameters:

p - the process into which the sub-process was embedded.

ci - the CatalogItem to be added to the Catalog.

Override:

Never

getResourceString

protected String getResourceString(String sKey)

Get the resource String for the specified key.

Override:

Sometimes The default implementation returns ""Please specify the CatalogItem's key:"" if asked for KEY_LABEL.
