Class ExecutionPlanJSONGenerator

java.lang.Object

org.apache.flink.optimizer.plandump.ExecutionPlanJSONGenerator

All Implemented Interfaces:

org.apache.flink.api.java.ExecutionPlanUtil.ExecutionPlanJSONGenerator

public class ExecutionPlanJSONGenerator
extends Object
implements org.apache.flink.api.java.ExecutionPlanUtil.ExecutionPlanJSONGenerator

Utility for extracting an execution plan (as JSON) from a given Plan.

We need this util here in the optimizer because it is the only module that has Optimizer, OptimizedPlan, and PlanJSONDumpGenerator available. We use this reflectively from the batch execution environments to generate the plan, which we cannot do there. It is used from ExecutionPlanUtil.
