public PendingItem(int sequenceNr)
```
- Method Detail
  - getSequenceNr
```
public int getSequenceNr()
```
    Get the sequence number of this item within a set of items representing nested nodes
    
    Returns:
    
    the sequence number
  - getGatherer
```
public abstract Receiver getGatherer()
                              throws XPathException
```
    Get a receiver which will be notified of all events in the streamed input between the start event for this node and the corresponding end event. This Receiver gathers data into the pending item so that the final result of processing the streamed node can be computed by the deliver() method
    
    Returns:
    
    a receiver to be notified of all events relating to this streamed input node
    
    Throws:
    
    XPathException - if a dynamic error is detected
  - deliver
```
public abstract Sequence deliver()
                          throws XPathException
```
    On completion of this streamed node, that is, when the relevant end tag is reached, compute the result of processing this node and return this result
    
    Returns:
    
    the result of processing a streamed input node
    
    Throws:
    
    XPathException - if the processing fails with a dynamic error
  - rollback
```
public abstract void rollback()
```
    Reset the data relating to this node if a dynamic error occurs while processing the input stream.
