- org.springframework.batch.core.jsr.partition.PartitionCollectorAdapter

所有已实现的接口:
ChunkListener, StepListener
```
public class PartitionCollectorAdapter
extends java.lang.Object
implements ChunkListener
```
Adapter class used to wrap a PartitionCollector so that it can be consumed as a ChunkListener. A thread-safe Queue is required along with the PartitionCollector. The Queue is where the result of the call to the PartitionCollector will be placed.

    从接口复制的说明: ChunkListener
    Callback before the chunk is executed, but inside the transaction.
    指定者:
    beforeChunk 在接口中 ChunkListener
    参数:
    context - The current ChunkContext
  - afterChunk
```
public void afterChunk(ChunkContext context)
```
    从接口复制的说明: ChunkListener
    Callback after the chunk is executed, outside the transaction.
    指定者:
    afterChunk 在接口中 ChunkListener
    参数:
    context - The current ChunkContext
  - afterChunkError
```
public void afterChunkError(ChunkContext context)
```
    从接口复制的说明: ChunkListener
    Callback after a chunk has been marked for rollback. It is invoked after transaction rollback. While the rollback will have occurred, transactional resources might still be active and accessible. Due to this, data access code within this callback will still "participate" in the original transaction unless it declares that it runs in its own transaction. Hence: Use PROPAGATION_REQUIRES_NEW for any transactional operation that is called from here.
    指定者:
    afterChunkError 在接口中 ChunkListener
    参数:
    context - the chunk context containing the exception that caused the underlying rollback.
