removeTermIteration
public abstract void removeTermIteration(Iterator<Statement> iter, Resource subj, IRI pred, Value obj, Resource... contexts)
Called by aggregate sets when a term has been removed from a term iterator. Exactly one of the last four terms will be non-empty.- Parameters:
iter
- The iterator used to navigate the live set (never null)subj
- the subject term to be removed or nullpred
- the predicate term to be removed or nullobj
- the object term to be removed or nullcontexts
- an array of one context term to be removed or an empty array
-
closeIterator
protected void closeIterator(Iterator<?> iter)
Cleans up any resources used by this iterator. After this call the given iterator should not be used.- Parameters:
iter
- Iterator to clean up
