Class RelParameterizerShuttle

java.lang.Object

org.apache.druid.sql.calcite.planner.RelParameterizerShuttle

All Implemented Interfaces:

org.apache.calcite.rel.RelShuttle

public class RelParameterizerShuttle
extends Object
implements org.apache.calcite.rel.RelShuttle

Traverse RelNode tree and replaces all RexDynamicParam with RexLiteral using RexBuilder if a value binding exists for the parameter. All parameters must have a value by the time RelParameterizerShuttle is run, or else it will throw an exception. Note: none of the tests currently hit this anymore since SqlParameterizerShuttle has been modified to handle most common jdbc types, but leaving this here provides a safety net to try again to convert parameters to literal values in case SqlParameterizerShuttle fails.
