Package edu.cornell.mannlib.vitro.webapp.edit.n3editing.VTwo

Class ProcessRdfForm

  • public class ProcessRdfForm
extends Object
    The goal of this class is to provide processing from an EditConfiguration and an EditSubmission to produce a set of additions and retractions. When working with the default object property form or the default data property from, the way to avoid having any optional N3 is to originally configure the configuration.setN3Optional() to be empty.

      • process

        public AdditionsAndRetractions process​(EditConfigurationVTwo configuration,
                                       MultiValueEditSubmission submission,
                                       VitroRequest vreq)
                                throws Exception
        This detects if this is an edit of an existing statement or an edit to create a new statement or set of statements. Then the correct method will be called to convert the EditConfiguration and EditSubmission into a set of additions and retractions. This will handle data property editing, object property editing and general editing. The submission object will be modified to have its entityToReturnTo string substituted with the values from the processing.
        Throws:
        Exception - May throw an exception if Required N3 does not parse correctly.

      • editExistingStatements

        protected AdditionsAndRetractions editExistingStatements​(EditConfigurationVTwo editConfig,
                                                         MultiValueEditSubmission submission,
                                                         VitroRequest vreq)
                                                  throws Exception
        Process an EditConfiguration to edit a set of existing statements. This will handle data property editing, object property editing and general editing. No longer checking if field has changed, because assertions and retractions are mutually diff'ed before statements are added to or removed from the model. The explicit change check can cause problems in more complex setups, like the automatic form building in DataStaR.
        Parameters:
        vreq - For getting linguistic context
        Throws:
        Exception
