```
public void cancel()
```
    Specified by:
    
    cancel in interface ExecutionGraph
  - suspend
```
public void suspend(Throwable suspensionCause)
```
    Description copied from interface: ExecutionGraph
    
    Suspends the current ExecutionGraph.
    The JobStatus will be directly set to JobStatus.SUSPENDED iff the current state is not a terminal state. All ExecutionJobVertices will be canceled and the onTerminalState() is executed.
    The JobStatus.SUSPENDED state is a local terminal state which stops the execution of the job but does not remove the job from the HA job store so that it can be recovered by another JobManager.
    
    Specified by:
    
    suspend in interface ExecutionGraph
    
    Parameters:
    
    suspensionCause - Cause of the suspension
  - failGlobal
```
public void failGlobal(Throwable t)
```
    Description copied from interface: InternalExecutionGraphAccessor
    
    Fails the execution graph globally.
    This global failure is meant to be triggered in cases where the consistency of the execution graph' state cannot be guaranteed any more (for example when catching unexpected exceptions that indicate a bug or an unexpected call race), and where a full restart is the safe way to get consistency back.
    
    Specified by:
    
    failGlobal in interface InternalExecutionGraphAccessor
    
    Parameters:
    
    t - The exception that caused the failure.
  - getArchivedExecutionConfig
```
public ArchivedExecutionConfig getArchivedExecutionConfig()
```
    Returns the serializable ArchivedExecutionConfig.
    
    Specified by:
    
    getArchivedExecutionConfig in interface AccessExecutionGraph
    
    Returns:
    
    ArchivedExecutionConfig which may be null in case of errors
  - getTerminationFuture
```
public CompletableFuture<JobStatus> getTerminationFuture()
```
    Description copied from interface: ExecutionGraph
    
    Returns the termination future of this ExecutionGraph. The termination future is completed with the terminal JobStatus once the ExecutionGraph reaches this terminal state and all Execution have been terminated.
    
    Specified by:
    
    getTerminationFuture in interface ExecutionGraph
    
    Returns:
    
    Termination future of this ExecutionGraph.

  - updateState
```
public boolean updateState(TaskExecutionStateTransition state)
```
    Description copied from interface: ExecutionGraph
