class CompareQuery[E: nullable Object]

for_abuse :: CompareQuery

A comparison query.

The user is asked to compare a with b then set res accordingly.

  • if a < b then the user sets res to -1
  • if a > b then the user sets res to 1
  • if a == b then the user sets res to 0

It is the responsibility of the user to implement a total order. ie. the implemented comparison must be asymmetric, transitive and total.
