Interface ItemAdminSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

All Known Subinterfaces:

ItemBatchAdminSession

public interface ItemAdminSession
extends OsidSession

This session creates, updates, and deletes Items. The data for create and update is provided by the consumer via the form object. OsidForms are requested for each create or update and may not be reused.

Create and update operations differ in their usage. To create a Item, a ItemForm is requested using getItemFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned ItemForm will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the ItemForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each ItemForm corresponds to an attempted transaction.

For updates, ItemForms are requested to the Item Id that is to be updated using getItemFormForUpdate(). Similarly, the ItemForm has metadata about the data that can be updated and it can perform validation before submitting the update. The ItemForm can only be used once for a successful update and cannot be reused.

The delete operations delete Items. To unmap a Item from the current Warehouse, the ItemWarehouseAssignmentSession should be used. These delete operations attempt to remove the Item itself thus removing it from all known Warehouse catalogs.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

Method Detail

getWarehouseId

Id getWarehouseId()

Gets the Warehouse Id associated with this session.

Returns:

the Warehouse Id associated with this session

Compliance:

mandatory - This method must be implemented.

getWarehouse

Warehouse getWarehouse()
                       throws OperationFailedException,
                              PermissionDeniedException

Gets the Warehouse associated with this session.

Returns:

the warehouse

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateItems

boolean canCreateItems()

Tests if this user can create Items. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating an Item will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer create operations to an unauthorized user.

Returns:

false if Item creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateItemWithRecordTypes

boolean canCreateItemWithRecordTypes(Type[] itemRecordTypes)

Tests if this user can create a single Item using the desired record types. While InventoryManager.getItemRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Item. Providing an empty array tests if an Item can be created with no records.

Parameters:

itemRecordTypes - array of item record types

Returns:

true if Item creation using the specified record Types is supported, false otherwise

Throws:

NullArgumentException - itemRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getItemFormForCreate

ItemForm getItemFormForCreate(Type[] itemRecordTypes)
                              throws OperationFailedException,
                                     PermissionDeniedException

Gets the item form for creating new items. A new form should be requested for each create transaction.

Parameters:

itemRecordTypes - array of item record types

Returns:

the item form

Throws:

NullArgumentException - itemRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createItem

Item createItem(ItemForm itemForm)
                throws OperationFailedException,
                       PermissionDeniedException

Creates a new Item.

Parameters:

itemForm - the form for this Item

Returns:

the new Item

Throws:

IllegalStateException - itemForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - itemForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - itemForm did not originate from getItemFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateItems

boolean canUpdateItems()

Tests if this user can update Items. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating an Item will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer update operations to an unauthorized user.

Returns:

false if Item modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getItemFormForUpdate

ItemForm getItemFormForUpdate(Id itemId)
                              throws NotFoundException,
