Interface ParameterProcessorLookupSession

All Superinterfaces:

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

public interface ParameterProcessorLookupSession
extends OsidSession

This session provides methods for retrieving ParameterProcessors.

This session defines views that offer differing behaviors when retrieving multiple objects.

• comparative view: elements may be silently omitted or re-ordered
• plenary view: provides a complete set or is an error condition
• isolated configuration view: All parameter processor methods in this session operate, retrieve and pertain to parameter processor defined explicitly in the current configuration. Using an isolated view is useful for managing ParameterProcessors with the ParameterProcessorAdminSession.
• federated configuration view: All parameter processor methods in this session operate, retrieve and pertain to all parameter processor defined in this configuration and any other parameter processor implicitly available in this configuration through configuration inheritence.
• active parameter processor view: All parameter processor lookup methods return active parameter processors.
• any status parameter processor view: Parameter processors of any active or inactive status are returned from methods.

Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods useFederatedDistributorView() and useIsolatedDistributorView() behave as a radio group and one should be selected before invoking the methods in this session.

mandatory - This method must be implemented.

canLookupParameterProcessors

boolean canLookupParameterProcessors()

Tests if this user can perform ParameterProcessors lookups. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a PERMISSION_DENIED. This is intended as a hint to an application that may opt not to offer lookup operations to unauthorized users.

Returns:

false if lookup methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useComparativeParameterProcessorView

void useComparativeParameterProcessorView()

The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.

Compliance:

mandatory - This method is must be implemented.

usePlenaryParameterProcessorView

void usePlenaryParameterProcessorView()

A complete view of the ParameterProcessor returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.

Compliance:

mandatory - This method is must be implemented.

useFederatedConfigurationView

void useFederatedConfigurationView()

Federates the view for methods in this session. A federated view will include parameter processor in configurations which are children of this configuration in the configuration hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedConfigurationView

void useIsolatedConfigurationView()

Isolates the view for methods in this session. An isolated view restricts lookups to this configuration only.

Compliance:

mandatory - This method is must be implemented.

useActiveParameterProcessorView

void useActiveParameterProcessorView()

Only active parameter processors are returned by methods in this session.

Compliance:

mandatory - This method is must be implemented.

useAnyStatusParameterProcessorView

void useAnyStatusParameterProcessorView()

All active and inactive parameter processors are returned by methods in this session.
