Interfaceosid.provisioning.QueueAdminSession
Implementsosid.OsidSession
Description

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

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

The delete operations delete Queues. To unmap a Queue from the current Distributor, the QueueDistributorAssignmentSession should be used. These delete operations attempt to remove the Queue itself thus removing it from all known Distributor catalogs.

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

MethodcanCreateQueueWithRecordTypes
Description

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

Parametersosid.type.Type[]queueRecordTypesarray of queue record types
Returnboolean true if Queue creation using the specified record Types is supported, false otherwise
ErrorsNULL_ARGUMENT queueRecordTypes is null
