Interface PollsAdminSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

All Known Subinterfaces:

PollsBatchAdminSession

public interface PollsAdminSession
extends OsidSession

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

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

The delete operations delete Polls .

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