Method Detail

preprocessModels

public static void preprocessModels(AdditionsAndRetractions changes,
                                    EditConfigurationVTwo editConfiguration,
                                    VitroRequest request)

Execute any modelChangePreprocessors in the editConfiguration;

getDefaultModelChangePreprocessors

public static List<ModelChangePreprocessor> getDefaultModelChangePreprocessors(VitroRequest vreq,
                                                                               org.apache.jena.rdf.model.Model displayModel)

Find which default model preprocessors are associated with the application. These will be run everytime an edit/addition occurs, i.e. whenever the preprocessModels method is called.

preprocessorForURI

public static ModelChangePreprocessor preprocessorForURI(VitroRequest vreq,
                                                         org.apache.jena.rdf.model.Model displayModel,
                                                         String preprocessorURI)
                                                  throws InstantiationException,
                                                         IllegalAccessException,

                                                         SecurityException

Returns a DataGetter using information in the displayModel for the individual with the URI given by dataGetterURI to configure it. May return null. This should not throw an exception if the URI exists and has a type that does not implement the DataGetter interface.

Throws:

InstantiationException

IllegalAccessException

ClassNotFoundException

IllegalArgumentException

InvocationTargetException

SecurityException

processEntityToReturnTo

public static String processEntityToReturnTo(EditConfigurationVTwo configuration,
                                             MultiValueEditSubmission submission,
                                             VitroRequest vreq)

Process Entity to Return to - substituting uris etc. May return null.

updateEditConfigurationForBackButton

public static void updateEditConfigurationForBackButton(EditConfigurationVTwo editConfig,
                                                        MultiValueEditSubmission submission,
                                                        VitroRequest vreq,
                                                        org.apache.jena.rdf.model.Model writeModel)
