    Parameters:
    execution - a JobExecution
  - getJobParametersIncrementer
```
@Nullable
JobParametersIncrementer getJobParametersIncrementer()
```
    If clients need to generate new parameters for the next execution in a sequence they can use this incrementer. The return value may be null, in the case that this job does not have a natural sequence.
    Returns:
    in incrementer to be used for creating new parameters
  - getJobParametersValidator
