Interface ChainLookupSession

All Superinterfaces:

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

public interface ChainLookupSession
extends OsidSession

This session defines methods for retrieving chains.

This lookup session defines several views:

• comparative view: elements may be silently omitted or re-ordered
• plenary view: provides a complete result set or is an error condition
• isolated antimatroid view: All chain methods in this session operate, retrieve and pertain to chains defined explicitly in the current antimatroid. Using an isolated view is useful for managing Chains with the ChainAdminSession.
• federated antimatroid view: All chain lookup methods in this session operate, retrieve and pertain to all chains defined in this antimatroid and any other chains implicitly available in this antimatroid through antimatroid inheritence.

The methods useFederatedAntimatroidView() and useIsolatedAntimatroidView() behave as a radio group and one should be selected before invoking any lookup methods.

Chains may have an additional records indicated by their respective record types. The record may not be accessed through a cast of the chains.

Method Detail

getAntimatroidId

Id getAntimatroidId()

Gets the Antimatroid Id associated with this session.

Returns:

the Antimatroid Id associated with this session

Compliance:

mandatory - This method must be implemented.

getAntimatroid

Antimatroid getAntimatroid()
                           throws OperationFailedException,
                                  PermissionDeniedException

Gets the Antimatroid associated with this session.

Returns:

the antimatroid

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canLookupChains

boolean canLookupChains()

Tests if this user can perform Chain 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 not offer lookup operations to unauthorized users.

Returns:

false if lookup methods are not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

useComparativeChainView

void useComparativeChainView()

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.

usePlenaryChainView

void usePlenaryChainView()

A complete view of the Chain 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.

useFederatedAntimatroidView

void useFederatedAntimatroidView()

Federates the view for methods in this session. A federated view will include chains in antimatroids which are children of this antimatroid in the antimatroid hierarchy.

Compliance:

mandatory - This method is must be implemented.

useIsolatedAntimatroidView

void useIsolatedAntimatroidView()

Isolates the view for methods in this session. An isolated view restricts retrievals to this antimatroid only.

Compliance:

mandatory - This method is must be implemented.

getChain

Chain getChain(Id chainId)
               throws NotFoundException,
                      OperationFailedException,
                      PermissionDeniedException

Gets the Chain specified by its Id. In plenary mode, the exact Id is found or a NOT_FOUND results. Otherwise, the returned Chain may have a different Id than requested, such as the case where a duplicate Id was assigned to a Chain and retained for compatibility.

Parameters:

chainId - the Id of the Chain to retrieve

Returns:

the returned Chain

Throws:

NotFoundException - no Chain found with the given Id

NullArgumentException - chainId is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

getChainsByIds

ChainList getChainsByIds(IdList chainIds)
                         throws NotFoundException,
                                OperationFailedException,
                                PermissionDeniedException

Gets a ChainList corresponding to the given IdList. In plenary mode, the returned list contains all of the chains specified in the Id list, in the order of the list, including duplicates, or an error results if an Id in the supplied list is not found or inaccessible. Otherwise, inaccessible Chains may be omitted from the list and may present the elements in any order including returning a unique set.
