Method Detail

determineInteractionModel

protected String determineInteractionModel(List<String> linkTypes,
                                           boolean isRdfContentType,
                                           boolean contentPresent,
                                           boolean isExternalContent)

Utility to determine the correct interaction model from elements of a request.

Parameters:

linkTypes - Link headers with rel="type"

isRdfContentType - Is the Content-type a known RDF type?

contentPresent - Is there content present on the request body?

isExternalContent - Is there Link headers that define external content?

Returns:

The determined or default interaction model.

checkAclLinkHeader

protected void checkAclLinkHeader(List<String> links)
                           throws RequestWithAclLinkHeaderException

Check that we don't try to provide an ACL Link header.

Parameters:

links - list of the link headers provided.

Throws:

RequestWithAclLinkHeaderException - If we provide an rel="acl" link header.

ensureValidDirectContainer

protected void ensureValidDirectContainer(FedoraId fedoraId,
                                          String interactionModel,
                                          org.apache.jena.rdf.model.Model model)

Verifies that DirectContainer properties are valid, throwing exceptions if the triples do not meet LDP requirements or a server managed property is specified as a membership relation. If no membershipResource or membership relation are specified, defaults will be populated.

Parameters:

fedoraId - id of the resource described

interactionModel - interaction model of the resource

model - model to check

ensureValidACLAuthorization

protected void ensureValidACLAuthorization(org.apache.jena.rdf.model.Model inputModel)

This method does two things: - Throws an exception if an authorization has both accessTo and accessToClass - Adds a default accessTo target if an authorization has neither accessTo nor accessToClass

Parameters:

inputModel - to be checked and updated

recordEvent

protected void recordEvent(Transaction transaction,
                           FedoraId fedoraId,
                           ResourceOperation operation)

updateReferences

protected void updateReferences(Transaction transaction,
                                FedoraId resourceId,
                                String user,
                                org.apache.jena.rdf.model.Model model)

Wrapper to call the referenceService updateReference method

Parameters:

transaction - the transaction.

resourceId - the resource's ID.

model - the model of the request body.

lockArchivalGroupResource

protected void lockArchivalGroupResource(Transaction tx,
                                         PersistentStorageSession pSession,
                                         FedoraId fedoraId)

lockParent

protected void lockParent(Transaction tx,
                          PersistentStorageSession pSession,
                          FedoraId parentId)
