Method Detail

getQueueId

Id getQueueId()

Gets the Queue Id associated with this session.

               throws OperationFailedException,

canCreateRequestsInExchange

boolean canCreateRequestsInExchange(Id provisionId)

Tests if this user can create Requests. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Request 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.

Parameters:

provisionId - the Id of the provision to exchange

Returns:

false if Request creation is not authorized, true otherwise

Throws:

NullArgumentException - provisionId is null

Compliance:

mandatory - This method must be implemented.

canCreateRequestWithRecordTypesInExchange

boolean canCreateRequestWithRecordTypesInExchange(Id provisionId,
                                                Type[] requestRecordTypes)

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

Parameters:

provisionId - the Id of the provision to exchange

requestRecordTypes - array of request record types

Returns:

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

Throws:

NullArgumentException - provisionId or requestRecordTypes is null

Compliance:

mandatory - This method must be implemented.

                                           OperationFailedException,
                                           PermissionDeniedException
