computeStreamability
public PostureAndSweep computeStreamability(ContextItemStaticInfoEE contextInfo, List<String> reasons) Get the "sweep" 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 classStreamingAdjunct
- Parameters:
contextInfo
- information about the context itemreasons
- 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 interfaceFeedMaker
- Throws:
XPathException
