public ChunkOrientedTasklet(ChunkProvider<I> chunkProvider,
                            ChunkProcessor<I> chunkProcessor)
```
- Method Detail
  - setBuffering
```
public void setBuffering(boolean buffering)
```
    Flag to indicate that items should be buffered once read. Defaults to true, which is appropriate for forward-only, non-transactional item readers. Main (or only) use case for setting this flag to false is a transactional JMS item reader.
    Parameters:
    buffering - indicator
  - execute
```
public RepeatStatus execute(StepContribution contribution,
                            ChunkContext chunkContext)
                     throws java.lang.Exception

    Description copied from interface: Tasklet
    Given the current context in the form of a step contribution, do whatever is necessary to process this unit inside a transaction. Implementations return RepeatStatus.FINISHED if finished. If not they return RepeatStatus.CONTINUABLE. On failure throws an exception.
    Specified by:
    execute in interface Tasklet
    Parameters:
    contribution - mutable state to be passed back to update the current step execution
    chunkContext - attributes shared between invocations but not between restarts
    Returns:
    an RepeatStatus indicating whether processing is continuable. Returning null is interpreted as RepeatStatus.FINISHED
    Throws:
    java.lang.Exception - thrown if error occurs during execution.
