- - org.springframework.batch.repeat.policy.DefaultResultCompletionPolicy
  - - org.springframework.batch.repeat.policy.SimpleCompletionPolicy

All Implemented Interfaces:
CompletionPolicy
```
public class SimpleCompletionPolicy
extends DefaultResultCompletionPolicy
```
Policy for terminating a batch after a fixed number of operations. Internal state is maintained and a counter incremented, so successful use of this policy requires that isComplete() is only called once per batch item. Using the standard RepeatTemplate should ensure this contract is kept, but it needs to be carefully monitored.

    Reset the counter.
    Specified by:
    start in interface CompletionPolicy
    Overrides:
    start in class CompletionPolicySupport
    Parameters:
    context - the current context if one is already in progress.
    Returns:
    a context object that can be used by the implementation to store internal state for a batch.

```
public boolean isComplete(RepeatContext context,
                          RepeatStatus result)
```
    Terminate if the chunk size has been reached, or the result is null.
    Specified by:
    isComplete in interface CompletionPolicy
    Overrides:
    isComplete in class DefaultResultCompletionPolicy
    Parameters:
    context - the current batch context.
    result - the result of the latest batch item processing.
    Returns:
    true if the batch should terminate.
    Throws:
    java.lang.RuntimeException - (normally terminating the batch) if the result is itself an exception.
