Class JdbcIntermediatePrel

java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.calcite.rel.SingleRel

org.apache.drill.exec.planner.physical.SinglePrel

org.apache.drill.exec.store.jdbc.JdbcIntermediatePrel

All Implemented Interfaces:

Cloneable, Iterable<Prel>, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.RelNode, DrillRelNode, Prel, PrelFinalizable

public class JdbcIntermediatePrel
extends SinglePrel
implements PrelFinalizable

Prel used to represent a JDBC Conversion within an expression tree. This Prel will replaced with a full JdbcPrel before execution can happen.
