Method Detail

getMapping

public FedoraOcflMapping getMapping(Transaction session,
                                    FedoraId fedoraResourceIdentifier)
                             throws FedoraOcflMappingNotFoundException

Description copied from interface: FedoraToOcflObjectIndex

Retrieve identification information for the OCFL object which either contains, or is identified by, the provided fedora resource id. In other words the method will find the closest resource that is persisted as an OCFL object and returns its identifiers. If you pass fedora identifier that is not part of an archival group such as "my/fedora/binary/fcr:metadata" the fedora resource returned in the mapping will be "my/fedora/binary". Contrast this with an Archival Group example: if you pass in "my/archival-group/binary/fcr:metadata" the resource returned in the mapping would be "my/archival-group".

Specified by:

getMapping in interface FedoraToOcflObjectIndex

Parameters:

session - the current session, or null for read-only.

fedoraResourceIdentifier - the fedora resource identifier

Returns:

the mapping

Throws:

FedoraOcflMappingNotFoundException - when no mapping exists for the specified identifier.
