Jena offers, among others, these methods on the UpdateModify class:
public void setElement(Element element) {
this.wherePattern = element ;
}
public QuadAcc getDeleteAcc() {
return deletePattern ;
}
public QuadAcc getInsertAcc() {
return insertPattern ;
}
Why can't I set the Delete- or Insert-pattern the same way I can set the
Where-pattern?
Or do I miss something?
