Interface BrokerAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

BrokerBatchAdminSession

public interface BrokerAdminSession
extends OsidSession

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

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

The delete operations delete Brokers. To unmap a Broker from the current Distributor, the BrokerDistributorAssignmentSession should be used. These delete operations attempt to remove the Broker 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.

getDistributorId

Id getDistributorId()

Gets the Distributor Id associated with this session.

the Distributor Id associated with this session

Compliance:

mandatory - This method must be implemented.

the distributor

boolean canCreateBrokers()

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

canCreateBrokerWithRecordTypes

boolean canCreateBrokerWithRecordTypes(Type[] brokerRecordTypes)

Tests if this user can create a single Broker using the desired record types.

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

Parameters:

brokerRecordTypes - array of broker record types

NullArgumentException - brokerRecordTypes is null

Compliance:

mandatory - This method must be implemented.
