TimestampedInputSplit (Flink : Runtime 2.1.1 API)

All Superinterfaces:

Comparable<TimestampedInputSplit>, org.apache.flink.core.io.InputSplit, Serializable

All Known Implementing Classes:

TimestampedFileInputSplit
```
public interface TimestampedInputSplit
extends org.apache.flink.core.io.InputSplit, Comparable<TimestampedInputSplit>
```
An extended InputSplit that also includes information about:
- The modification time of the file this split belongs to.
- When checkpointing, the state of the split at the moment of the checkpoint.
This class is used by the ContinuousFileMonitoringFunction and the ContinuousFileReaderOperator to perform continuous file processing.

- Method Detail
  - setSplitState
```
void setSplitState(Serializable state)
```
    Sets the state of the split. This information is used when restoring from a checkpoint and allows to resume reading the underlying file from the point we left off.
    * This is applicable to FileInputFormats that implement the CheckpointableInputFormat interface.
  - getSplitState
```
Serializable getSplitState()
```
    Returns:
    
    the state of the split.
  - resetSplitState
```
default void resetSplitState()
```
    Sets the state of the split to null.
  - getModificationTime
```
long getModificationTime()
```
    Returns:
    
    The modification time of the file this split belongs to.
