    Method
    Description
    protected void
    checkAclLinkHeader(List<String> links)
    Check that we don't try to provide an ACL Link header.
    protected String
    determineInteractionModel(List<String> linkTypes, boolean isRdfContentType, boolean contentPresent, boolean isExternalContent)
    Utility to determine the correct interaction model from elements of a request.
    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
    protected void
    ensureValidDirectContainer(org.fcrepo.kernel.api.identifiers.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.

    • 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 org.fcrepo.kernel.api.exception.RequestWithAclLinkHeaderException
      Check that we don't try to provide an ACL Link header.
      Parameters:
      links - list of the link headers provided.
      Throws:
      org.fcrepo.kernel.api.exception.RequestWithAclLinkHeaderException - If we provide an rel="acl" link header.

    • ensureValidDirectContainer

      protected void ensureValidDirectContainer(org.fcrepo.kernel.api.identifiers.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 updateReferences(org.fcrepo.kernel.api.Transaction transaction, org.fcrepo.kernel.api.identifiers.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.
