INSERT and DELETE content

Adding an INSERT, INSERT DATA, or DELETE form can be performed through the following methods:

• The ISparqlRequestGroup.addInsert() method adds an INSERT form
• The ISparqlRequestGroup.addInsertData() method adds an INSERT DATA form
• The ISparqlRequestGroup.addDelete() method adds a DELETE form

The resulting form can be used to add expressions. For example:

   SparqlRequest request = new SparqlRequest("people");
   request.addAdditionalVariable("person");
   request.addType("person", "Person");
      
   DeleteForm delete = request.addDelete();
   request.addAdditionalVariable("friend");
   delete.addPropertyRef("person", "hasFriend", "friend");
      
   InsertForm insert = request.addInsert();
   insert.addPropertyValue("person", "hasFriend", "Paul");
      
   String sparql = request.getSPARQL();

Will have the following result:

   DELETE {
      ?person people:hasFriend ?friend .
   }
   INSERT {
      ?person people:hasFriend "Paul" .
   }
   WHERE {
      ?person rdf:type people:Person .
   }
