End a membership entry, setting an end time if committed, or clearing from the current tx if it was newly added.

Parameters:

txId - transaction id

sourceId - ID of the direct/indirect container whose membership should be ended

membership - membership triple to end

endTime - the time the resource was deleted, generally its last modified

endMembershipForSource

public void endMembershipForSource(String txId,

End all membership properties resulting from the specified source container

Parameters:

txId - transaction id

sourceId - ID of the direct/indirect container whose membership should be ended

endTime - the time the resource was deleted, generally its last modified

deleteMembershipForSourceAfter

Delete membership entries that are active at or after the given timestamp for the specified source

Parameters:

txId - transaction id

sourceId - ID of the direct/indirect container

afterTime - time at or after which membership should be removed

deleteMembershipReferences

public void deleteMembershipReferences(String txId,
                                       org.fcrepo.kernel.api.identifiers.FedoraId targetId)
