SavepointRuntimeContext (flink-state-processor-api 1.10.1 API)

java.lang.Object
- org.apache.flink.state.api.runtime.SavepointRuntimeContext

所有已实现的接口:

org.apache.flink.api.common.functions.RuntimeContext
```
@Internal
public final class SavepointRuntimeContext
extends Object
implements org.apache.flink.api.common.functions.RuntimeContext
```
A streaming RuntimeContext which delegates to the underlying batch RuntimeContext along with a specified KeyedStateStore.
This RuntimeContext has the ability to force eager state registration by throwing an exception if state is registered outside of open.
