public class QueryEvaluator<T, R>:

QueryEvaluator

Optimized canonical evaluator shared by in-memory query executions.

The evaluator works directly on specialized generic rows. Values are boxed only for heterogeneous ordering keys and structural distinctness.

rows = QueryEvaluator.evaluate(sourceRows, plan)
