Class OptimizedPlan

java.lang.Object

org.apache.flink.compiler.plan.OptimizedPlan

All Implemented Interfaces:

Visitable<PlanNode>

public class OptimizedPlan
extends Object
implements Visitable<PlanNode>

The optimizer representation of a plan. The optimizer creates this from the user defined PACT job plan. It works on this representation during its optimization. Finally, this plan is translated to a schedule for the nephele runtime system.
