```
public interface StreamOperatorStateContext
```
This interface represents a context from which a stream operator can initialize everything connected to state such as e.g. backends, raw state, and timer service manager.

  - isRestored
```
default boolean isRestored()
```
    Returns true if the states provided by this context are restored from a checkpoint/savepoint.
  - getRestoredCheckpointId
```
OptionalLong getRestoredCheckpointId()
```
    Returns non-empty if the states provided by this context are restored from a checkpoint/savepoint.
  - operatorStateBackend
```
OperatorStateBackend operatorStateBackend()
```
    Returns the operator state backend for the stream operator.
  - keySerializer
```
org.apache.flink.api.common.typeutils.TypeSerializer<?> keySerializer()
```
    Returns the key serializer for keyed state backends.
  - keyedStateBackend
```
CheckpointableKeyedStateBackend<?> keyedStateBackend()
```
    Returns the keyed state backend for the stream operator. This method returns null for non-keyed operators.
  - asyncKeyedStateBackend
```
AsyncKeyedStateBackend<?> asyncKeyedStateBackend()
```
    Returns the async keyed state backend for the stream operator. This method returns null for operators which don't support async keyed state backend.
  - internalTimerServiceManager
```
InternalTimeServiceManager<?> internalTimerServiceManager()
```
    Returns the internal timer service manager for the stream operator. This method returns null for non-keyed operators.
  - asyncInternalTimerServiceManager
```
InternalTimeServiceManager<?> asyncInternalTimerServiceManager()
```
    Returns the internal timer service manager create by async state backend for the stream operator. This method returns null for non-keyed operators.
  - rawOperatorStateInputs
```
org.apache.flink.util.CloseableIterable<StatePartitionStreamProvider> rawOperatorStateInputs()
```
    Returns an iterable to obtain input streams for previously stored operator state partitions that are assigned to this stream operator.
  - rawKeyedStateInputs
```
org.apache.flink.util.CloseableIterable<KeyGroupStatePartitionStreamProvider> rawKeyedStateInputs()
```
    Returns an iterable to obtain input streams for previously stored keyed state partitions that are assigned to this operator. This method returns null for non-keyed operators.
