public class BackorderProcessor : RequestItemProcessorConstructors
BackorderProcessor(InventoryRequest, InventoryRequestItem, OperationKeySerializer, RecordStateSet)
Creates a new instance of BackorderProcessor.
Declaration
public BackorderProcessor(InventoryRequest request, InventoryRequestItem requestItem, OperationKeySerializer operationKeySerializer, RecordStateSet recordStateSet)Parameters
| Type | Name | Description |
|---|---|---|
| InventoryRequest | request | The request containing the item to process. |
| InventoryRequestItem | requestItem | The request item to process. |
| OperationKeySerializer | operationKeySerializer | The OperationKeySerializer for encoding and decoding operation keys. |
| RecordStateSet | recordStateSet | The collection of RecordState values for the request. |
Methods
Apply()
Applies the request item to the appropriate RecordState.
Declaration
public override void Apply()Overrides
Remarks
The backorder request item will be marked as a failure if the request date is before either PurchaseAvailableUtc or BackorderAvailableUtc, of if IsTracked is false (untracked items cannot be out of stock, so they cannot be backordered).
Successful backorders will apply quantity changes from GetPostValidateChanges().
GetPostValidateChanges()
Returns the changes applied by the request item.
Declaration
public override IEnumerable<InventoryChange> GetPostValidateChanges()Returns
| Type | Description |
|---|---|
| System.Collections.Generic.IEnumerable<InventoryChange> |
Overrides
Remarks
Successful backorder requests move quantity from BackorderAvailableQuantity to BackorderRequestedQuantity.
Backorder requests apply changes after validation because the BackorderAvailableQuantity value is permitted to go into the negative. If one backorder quantity is available, and a request contains two items backordering five each, the request should succeed -- backorder available is a soft limit since it is not a paid promise to purchase; it is more of a suggestion that the item is in demand. The changes are applied after validation so that the Validate() can verify that the original available quantity is greater than zero, and not that the final available quantity is greater than zero.
GetResponseItems(Boolean)
Returns the final InventoryResponseItem instances for the item (typically, only one unless the operation is a split). CreateDefaultResponseItem(InventoryRequestItem, Boolean, RecordState, String, InventoryResponseType, InventoryResponseTypeInfo) can be used to generate response items in most cases.
Declaration
public override InventoryResponseItem[] GetResponseItems(bool isOverallSuccess)Parameters
| Type | Name | Description |
|---|---|---|
| System.Boolean | isOverallSuccess | True if all items wer successful, false if any item returned false from Validate(). |
Returns
| Type | Description |
|---|---|
| InventoryResponseItem[] |
Overrides
Validate()
Validates that the request item is successful.
Declaration
public override bool Validate()Returns
| Type | Description |
|---|---|
| System.Boolean | True if the request item is successful; otherwise, false. |
Overrides
Remarks
The backorder request item will be successful if the conditions in Apply() are met, and BackorderAvailableQuantity is greater than zero at the beginning of the request.
