Class RelTimeIndicatorConverter

java.lang.Object

org.apache.calcite.rel.RelShuttleImpl

org.apache.calcite.rel.RelHomogeneousShuttle

org.apache.flink.table.planner.calcite.RelTimeIndicatorConverter

All Implemented Interfaces:

org.apache.calcite.rel.RelShuttle

public final class RelTimeIndicatorConverter
extends org.apache.calcite.rel.RelHomogeneousShuttle

Traverses a 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.
