[jira] [Created] (JENA-1752) QueryBuilders should support (NOT) EXISTS clause

Jan Martin Keil created JENA-1752:
-------------------------------------

             Summary: QueryBuilders should support (NOT) EXISTS clause
                 Key: JENA-1752
                 URL: https://issues.apache.org/jira/browse/JENA-1752
             Project: Apache Jena
          Issue Type: Improvement
            Reporter: Jan Martin Keil


To support (NOT) EXISTS clauses, I propose to add to the classes
 * {{org.apache.jena.arq.querybuilder.AskBuilder}}
 * {{org.apache.jena.arq.querybuilder.ConstructBuilder}}
 * {{org.apache.jena.arq.querybuilder.SelectBuilder}}

the following methods
 * {{addExists(Element el)}}
 * {{addNotExists(Element el)}}
