public CompositeItemStream()
```
- 方法详细资料
  - setStreams
```
public void setStreams(ItemStream[] streams)
```
    Public setter for the ItemStreams.
    参数:
    streams - array of ItemStream.
  - register
```
public void register(ItemStream stream)
```
    Register a ItemStream as one of the interesting providers under the provided key.
    参数:
    stream - an instance of ItemStream to be added to the list of streams.
  - update
```
public void update(ExecutionContext executionContext)
```
    Simple aggregate ExecutionContext provider for the contributions registered under the given key.
    指定者:
    update 在接口中 ItemStream
    参数:
    executionContext - to be updated
    另请参阅:
    ItemStream.update(ExecutionContext)
  - close
```
public void close()
           throws ItemStreamException
```
    Broadcast the call to close.
    指定者:
    close 在接口中 ItemStream
    抛出:
    ItemStreamException - thrown if one of the ItemStreams in the list fails to close. This is a sequential operation so all itemStreams in the list after the one that failed to close will remain open.
  - open
```
public void open(ExecutionContext executionContext)
          throws ItemStreamException
```
    Broadcast the call to open.
    指定者:
    open 在接口中 ItemStream
    参数:
    executionContext - current step's ExecutionContext. Will be the executionContext from the last run of the step on a restart.
    抛出:
    ItemStreamException - thrown if one of the ItemStreams in the list fails to open. This is a sequential operation so all itemStreams in the list after the one that failed to open will not be opened.
