getOrder

ComputerOrder getOrder()

Specifies the kind of computer that is being ordered. This field returns the kind of computer that the user is requesting. If this is a new order, then this is the kind of computer that needs to be built. If this is a change order, then this specifies what the customer wants now; the previously existing order type should be abandoned and replaced with this new order type. If this CIT is a cancellation order, then getOrder is meaningless and should be ignored.

Returns:

Type of computer that the customer wants.

getPrevTransactionReceipt

OrderReceipt<S> getPrevTransactionReceipt()

This field allows this CIT to specify a change to an existing order. If this is a new order, then this returns null. Otherwise, it returns the receipt that was previously generated by the plant when the order was first established.

Returns:

null if this is a new order; otherwise the receipt from a previous order, if this is a change order.

isCancellation

boolean isCancellation()

Specifies whether this is a cancellation of a previously existing order. If it is, then the previous order can be identified via getPrevTransactionReceipt().

Returns:

true iff this is a cancellation of a standing order.
