Class representing a pointer to the result set of a query on a MongoDB server.
Clients can iterate through a cursor::iterator to retrieve results.
iterator mongocxx::v_noabi::cursor::begin | ( | ) |
A cursor::iterator that points to the beginning of any available results.
If begin() is called more than once, the cursor::iterator returned points to the next remaining result, not the result of the original call to begin().
For a tailable cursor, when cursor.begin() == cursor.end(), no documents are available. Each call to cursor.begin() checks again for newly-available documents.
mongocxx::v_noabi::query_exception | if the query failed |
iterator mongocxx::v_noabi::cursor::end | ( | ) |
A cursor::iterator indicating cursor exhaustion, meaning that no documents are available from the cursor.
