public final class RelTimeIndicatorConverter
extends org.apache.calcite.rel.RelHomogeneousShuttle
RelNode
tree and converts fields with TimeIndicatorRelDataType
type.
If a time attribute is accessed for a calculation, it will be materialized. Forwarding is allowed
in some cases, but not all.Modifier and Type | Method and Description |
