List of oneTimeIterator() Examples

Examples of oneTimeIterator()

lupos.datastructures.queryresult.QueryResult.oneTimeIterator()
Because of optimization purposes, you must call this method only once, because the iterator returned from a second call of the method may forget bindings. This is not the case for this QueryResult class, but for some derived classes like IteratorQueryResult, which are used in order not to store unnecessarily intermediate data on disk!

Examples of lupos.datastructures.queryresult.QueryResult.oneTimeIterator()

        final QueryResult zQueryResult = queryResult;
