Interface CreditAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

CreditBatchAdminSession

public interface CreditAdminSession
extends OsidSession

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

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

The delete operations delete Credits. To unmap a Credit from the current Billing, the CreditBillingAssignmentSession should be used. These delete operations attempt to remove the Credit itself thus removing it from all known Billing catalogs.

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

                   throws OperationFailedException,
                          PermissionDeniedException

Gets the Billing associated with this session.

Returns:

the billing

Throws:

OperationFailedException - unable to complete request

Providing an empty array tests if a Credit can be created with no records.

Parameters:

creditRecordTypes - array of credit record types

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