AdaptiveGraphGenerator (Flink : Runtime 2.1.0 API)

All Known Implementing Classes:

AdaptiveGraphManager
```
@Internal
public interface AdaptiveGraphGenerator
```
Defines the mechanism for dynamically adapting the graph topology of a Flink job at runtime. The AdaptiveGraphGenerator is responsible for managing and updating the job's execution plan based on runtime events such as the completion of a job vertex. It provides functionalities to generate new job vertices, retrieve the current JobGraph, update the StreamGraph, and track the status of pending stream nodes.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`JobGraph`	`getJobGraph()`	Retrieves the JobGraph representation of the current state of the Flink job.
`StreamGraphContext`	`getStreamGraphContext()`	Retrieves the StreamGraphContext which provides a read-only view of the StreamGraph and methods to modify its StreamEdges and StreamNodes.
`List<JobVertex>`	`onJobVertexFinished(JobVertexID finishedJobVertexId)`	Responds to notifications that a JobVertex has completed execution.

- Method Detail
  - getJobGraph
```
JobGraph getJobGraph()
```
    Retrieves the JobGraph representation of the current state of the Flink job.
    
    Returns:
    
    The JobGraph instance.
  - getStreamGraphContext
```
StreamGraphContext getStreamGraphContext()
```
    Retrieves the StreamGraphContext which provides a read-only view of the StreamGraph and methods to modify its StreamEdges and StreamNodes.
    
    Returns:
    
    an instance of StreamGraphContext.
  - onJobVertexFinished
```
List<JobVertex> onJobVertexFinished(JobVertexID finishedJobVertexId)
```
    Responds to notifications that a JobVertex has completed execution. This method generates new job vertices, incorporates them into the JobGraph, and returns a list of the newly created JobVertex instances.
    
    Parameters:
    
    finishedJobVertexId - The ID of the completed JobVertex.
    
    Returns:
    
    A list of the newly added JobVertex instances to the JobGraph.
