Interface MeterAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

MeterBatchAdminSession

public interface MeterAdminSession
extends OsidSession

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

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

The delete operations delete Meters. To unmap a Meter from the current Utility, the MeterUtilityAssignmentSession should be used. These delete operations attempt to remove the Meter itself thus removing it from all known Utility catalogs.

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

Method Detail

getUtilityId

Id getUtilityId()

Gets the Utility Id associated with this session.

Returns:

the Utility Id associated with this session

Compliance:

mandatory - This method must be implemented.

                   throws OperationFailedException,
                          PermissionDeniedException

Gets the Utility associated with this session.

Returns:

the Utility associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateMeters

boolean canCreateMeters()

Tests if this user can create Meters A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Meter 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 Meter creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateMeterWithRecordTypes

boolean canCreateMeterWithRecordTypes(Type[] meterRecordTypes)

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

Parameters:

meterRecordTypes - array of meter record types

Returns:

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

Throws:

NullArgumentException - meterRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getMeterFormForCreate

MeterForm getMeterFormForCreate(Type[] meterRecordTypes)
                                throws OperationFailedException,
                                       PermissionDeniedException

Gets the meter form for creating new meters. A new form should be requested for each create transaction.

Parameters:

meterRecordTypes - array of meter record types

Returns:

the meter form

Throws:

NullArgumentException - meterRecordTypes 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.

createMeter

Meter createMeter(MeterForm meterForm)
                  throws OperationFailedException,
                         PermissionDeniedException

Creates a new Meter.

Parameters:

meterForm - the form for this Meter

Returns:

the new Meter

Throws:

IllegalStateException - meterForm already used in a create transaction

InvalidArgumentException - one or more of the form elements is invalid

NullArgumentException - meterForm is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - meterForm did not originate from getMeterFormForCreate()

Compliance:

mandatory - This method must be implemented.

canUpdateMeters

boolean canUpdateMeters()

Tests if this user can update Meters. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a Meter 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 Meter modification is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getMeterFormForUpdate

MeterForm getMeterFormForUpdate(Id meterId)
                                throws NotFoundException,
