public interface IQueryOptions extends Serializable
IStepwhen evaluated as a query.
|Modifier and Type||Method and Description|
An optional array of
DistinctFiltershould be applied when the query is evaluated.
ISortOrders describing the sort order that will be imposed on the generated solutions when the rule is evaluated as a query.
nulliff there is no "order by" constraint.
ISlicedescribing a constraint on the first solution and the maximum #of solutions to be materialized by a query.
Note: Using an
ISlice requires that the solutions are stable
for queries against the same commit point of the database.
nullif there is no constraint on the solutions that will be visited.
trueiff query evaluation must be stable. Stable query evaluation requires that the same query executed against the same commit point will produce the same solutions in the same order. This constraint requires that (a) query execution does not use any parallelism; and (b) all
IStepTaskare determinate. Stable queries may be useful when using an
ISliceto page through a solution set.
trueif query evaluation must be stable.
