boolean edu.tum.cs.ias.knowrob.json_prolog.PrologQueryProxy.QueryIterator.hasNext ( ) [inline]

Check if there are any more results; retrieves new results from json_prolog if available.

Definition at line 157 of file PrologQueryProxy.java.

PrologBindings edu.tum.cs.ias.knowrob.json_prolog.PrologQueryProxy.QueryIterator.next ( ) [inline]

Return the next element in the list. hasNext makes sure there is a next elment.

boolean edu.tum.cs.ias.knowrob.json_prolog.PrologQueryProxy.QueryIterator.requestNextSolution ( ) [inline, protected]

Check if there is a next solution, either already in the list data_ or available via json_prolog

Returns:: True if there is a next solution (which is being added to the data_ buffer)
