方法详细资料

getExternalPointer

public String getExternalPointer()

从接口复制的说明: CompletedCheckpointStorageLocation

Gets the external pointer to the checkpoint. The pointer can be used to resume a program from the savepoint or checkpoint, and is typically passed as a command line argument, an HTTP request parameter, or stored in a system like ZooKeeper.

指定者:

getExternalPointer 在接口中 CompletedCheckpointStorageLocation

getExclusiveCheckpointDir

public org.apache.flink.core.fs.Path getExclusiveCheckpointDir()

getMetadataHandle

public FileStateHandle getMetadataHandle()

从接口复制的说明: CompletedCheckpointStorageLocation

Gets the state handle to the checkpoint's metadata.

指定者:

getMetadataHandle 在接口中 CompletedCheckpointStorageLocation

disposeStorageLocation

public void disposeStorageLocation()
                            throws IOException

从接口复制的说明: CompletedCheckpointStorageLocation

Disposes the storage location. This method should be called after all state objects have been released. It typically disposes the base structure of the checkpoint storage, like the checkpoint directory.

指定者:

disposeStorageLocation 在接口中 CompletedCheckpointStorageLocation

抛出:

IOException
