修饰符和类型	方法	说明
`boolean`	`isComplete(RepeatContext context)`	Allow policy to signal completion according to internal state, without having to wait for the callback to complete.
`boolean`	`isComplete(RepeatContext context, RepeatStatus result)`	Determine whether a batch is complete given the latest result from the callback.
`RepeatContext`	`start(RepeatContext parent)`	Create a new context for the execution of a batch.
`void`	`update(RepeatContext context)`	If `CheckpointAlgorithm.isReadyToCheckpoint()` is true we will call `CheckpointAlgorithm.endCheckpoint()`

    从接口复制的说明: CompletionPolicy
    Determine whether a batch is complete given the latest result from the callback. If this method returns true then CompletionPolicy.isComplete(RepeatContext) should also (but not necessarily vice versa, since the answer here depends on the result).
    指定者:
    isComplete 在接口中 CompletionPolicy
    参数:
    context - the current batch context.
    result - the result of the latest batch item processing.
    返回:
    true if the batch should terminate.

```
public boolean isComplete(RepeatContext context)
```
    从接口复制的说明: CompletionPolicy
    Allow policy to signal completion according to internal state, without having to wait for the callback to complete.
    指定者:
    isComplete 在接口中 CompletionPolicy
    参数:
    context - the current batch context.
    返回:
    true if the batch should terminate.
  - start
```
public RepeatContext start(RepeatContext parent)
```
    从接口复制的说明: CompletionPolicy
    Create a new context for the execution of a batch. N.B. implementations should not return the parent from this method - they must create a new context to meet the specific needs of the policy. The best way to do this might be to override an existing implementation and use the RepeatContext to store state in its attributes.
    指定者:
    start 在接口中 CompletionPolicy
    参数:
    parent - the current context if one is already in progress.
    返回:
    a context object that can be used by the implementation to store internal state for a batch.
  - update
```
public void update(RepeatContext context)
```
    If CheckpointAlgorithm.isReadyToCheckpoint() is true we will call CheckpointAlgorithm.endCheckpoint()
    指定者:
    update 在接口中 CompletionPolicy
    参数:
    context - a RepeatContext
