    Description copied from class: ItemFeed
    
    Start evaluating the expression. The default implementation does nothing.
    
    Overrides:
    
    open in class ItemFeed
    
    Parameters:
    
    terminator - used to achieve early exit
    
    Throws:
    
    XPathException - if a dynamic error occurs
  - append
```
public void append(Item item)
            throws XPathException

    Supply an item to the feed
    
    Specified by:
    
    append in interface Receiver
    
    Specified by:
    
    append in class ItemFeed
    
    Parameters:
    
    item - the item being fed (in this case, an item in the "pushed" operand sequence that is being compared
    
    Throws:

  - close
```
public void close()
           throws XPathException
```
