virtual bool QUICK_ROR_UNION_SELECT::is_valid | ( | ) | [inline, virtual] |
Simple sanity check that the quick select has been set up correctly. Function is overridden by quick selects that merge indices.
Reimplemented from QUICK_SELECT_I.
bool QUICK_ROR_UNION_SELECT::reverse_sort_possible | ( | ) | const [inline, virtual] |
Whether the range access method is capable of returning records in reverse order.
Implements QUICK_SELECT_I.
bool QUICK_ROR_UNION_SELECT::reverse_sorted | ( | ) | const [inline, virtual] |
Whether the range access method returns records in reverse order.
Implements QUICK_SELECT_I.
