Member Function Documentation

virtual bool QUICK_ROR_INTERSECT_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_INTERSECT_SELECT::reverse_sort_possible ( ) const [inline, virtual]

Whether the range access method is capable of returning records in reverse order.

bool QUICK_ROR_INTERSECT_SELECT::reverse_sorted ( ) const [inline, virtual]

Whether the range access method returns records in reverse order.
