Interface UtilityAdminSession

All Superinterfaces:

All Known Subinterfaces:

public interface UtilityAdminSession
extends OsidSession

This session creates, updates, and deletes Utilities. 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 UtilityForm, a UtilityForm is requested using getUtilityFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned UtilityForm 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 UtilityForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each UtilityForm corresponds to an attempted transaction.

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

The delete operations delete Utilities.

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

Method Detail

canCreateUtilities

boolean canCreateUtilities()

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

Returns:

false if Utility creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateUtilityWithRecordTypes

boolean canCreateUtilityWithRecordTypes(Type[] utilityRecordTypes)

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

Parameters:

utilityRecordTypes - array of utility record types

Returns:

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

Throws:

NullArgumentException - utilityRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getUtilityFormForCreate

UtilityForm getUtilityFormForCreate(Type[] utilityRecordTypes)
                                    throws OperationFailedException,
                                           PermissionDeniedException

Gets the utility form for creating new utilities. A new form should be requested for each create transaction.

Parameters:

utilityRecordTypes - array of utility record types

Returns:

the utility form

Throws:

NullArgumentException - utilityRecordTypes 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.

createUtility

Utility createUtility(UtilityForm utilityForm)
                      throws OperationFailedException,
                             PermissionDeniedException

Creates a new Utility.

Parameters:

utilityForm - the form for this Utility

Returns:

the new Utility

Throws:

IllegalStateException - utilityForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - utilityForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - utilityForm did not originate from getUtilityFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateUtilities

boolean canUpdateUtilities()

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

Returns:

false if Utility modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getUtilityFormForUpdate

UtilityForm getUtilityFormForUpdate(Id utilityId)
                                    throws NotFoundException,
                                           OperationFailedException,
                                           PermissionDeniedException

Gets the utility form for updating an existing utility. A new utility form should be requested for each update transaction.

Parameters:

utilityId - the Id of the Utility

Returns:

the utility form

Throws:

NotFoundException - utilityId is not found

NullArgumentException - utilityId is null

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

updateUtility

void updateUtility(UtilityForm utilityForm)
                   throws OperationFailedException,
                          PermissionDeniedException

Updates an existing utility.

boolean canManageUtilityAliases()

Tests if this user can manage Id aliases for utilities. A return of true does not guarantee successful authorization.
