- Method Detail
  - computeStreamability
```
public PostureAndSweep computeStreamability(ContextItemStaticInfoEE contextInfo,
                                            java.util.List<java.lang.String> reasons)
```
    Get the sweep and posture of this expression as defined in the W3C streamability specifications. This provides an assessment of stylesheet code against the W3C criteria for guaranteed streamability, and is implemented to allow these criteria to be tested. It is not the case that all expression that emerge as streamable from this analysis are currently capable of being streamed by Saxon
    
    Overrides:
    
    computeStreamability in class StreamingAdjunct
    
    Parameters:
    
    contextInfo - information about the context item type and posture
    
    reasons - the caller may supply a list, in which case the implementation may add to this
    
    Returns:
    
    the posture and sweep of the expression
  - makeItemFeed
```
public ItemFeed makeItemFeed(WatchManager watchManager,
                             ItemFeed out,
                             XPathContext context)
                      throws XPathException
```
    Specified by:
    
    makeItemFeed in interface FeedMaker
    
    Throws:
    
    XPathException
