IncrementalDataSourceScanner (platform/sdk 5.6.1.0 API)

```
public interface IncrementalDataSourceScanner
```
Interface for scanners to implement if they want to support incremental scanning. The implementation of the interface provides standard configuration and reset() in the Administration UI. However, the scanner must implement incremental logic using IngestionHistoryApi to persist the state of the scan between runs. See the SampleIncrementalDataSourceScanner SDK example.

- Method Detail
  - isIncrementalDeletes
```
boolean isIncrementalDeletes()
```
    Returns:
    
    true if document auto delete is enabled.
  - setIncrementalDeletes
```
void setIncrementalDeletes(boolean autoDelete)
```
    Specifies whether to delete Attivio documents when their underlying data source documents were deleted. This setting is only valid if setIncrementalModeActivated(boolean) is set to true.
    
    Parameters:
    
    autoDelete - if true, will automatically delete documents that no longer exist.
  - reset
```
void reset()
    throws AttivioException
```
    Resets any state being maintained by this scanner.
    
    Throws:
    
    AttivioException
  - isIncrementalModeActivated
```
boolean isIncrementalModeActivated()
```
    Whether or not this scanner should run in incremental mode.
    
    Returns:
    
    current state of incremental mode activation.
  - setIncrementalModeActivated
```
void setIncrementalModeActivated(boolean incrementalModeActivated)
```
    Specifies whether or not this scanner should run in incremental mode.
    
    Parameters:
    
    incrementalModeActivated - a toggle value indicating whether or not this scanner should run in incremental mode.
