Interface Ordering

All Known Implementing Classes:
OrderingImpl
public interface Ordering
Determines the relative order of two node-tuples by evaluating operand for each.

For a first node-tuple, nt1, for which operand evaluates to v1, and a second node-tuple, nt2, for which operand evaluates to v2:

  • If order is Ascending, then:
    • if either v1 is null, v2 is null, or both v1 and v2 are null, the relative order of nt1 and nt2 is implementation determined, otherwise
    • if v1 is a different property type than v2, the relative order of nt1 and nt2 is implementation determined, otherwise
    • if v1 is ordered before v2, then nt1 precedes nt2, otherwise
    • if v1 is ordered after v2, then nt2 precedes nt1, otherwise
    • the relative order of nt1 and nt2 is implementation determined and may be arbitrary.
  • Otherwise, if order is Descending, then:
    • if either v1 is null, v2 is null, or both v1 and v2 are null, the relative order of nt1 and nt2 is implementation determined, otherwise
    • if v1 is a different property type than v2, the relative order of nt1 and nt2 is implementation determined, otherwise
    • if v1 is ordered before v2, then nt2 precedes nt1, otherwise
    • if v1 is ordered after v2, then nt1 precedes nt2, otherwise
    • the relative order of nt1 and nt2 is implementation determined and may be arbitrary.
