Method Detail

getSortFrontier

public boolean getSortFrontier()

Returns false. The openrdf Value interface does not implement Comparable and can not be sorted without an external Comparator. Also, the order over the external RDF Value representations is unlikely to benefit any Sail that uses disk-based indices since the on-disk indices typically use a different order, e.g., over int identifiers.
