public interface FeedMaker

An expression that can be evaluated in streaming mode is represented at compile time by a list of FeedMaker objects. At run-time, the makeItemFeed(WatchManager, ItemFeed, XPathContext) method on each of these objects is called to create a list of ItemFeed objects, representing the evaluation pipeline. The output of the Watch that monitors the actual parsing events is then fed into this pipeline, which eventually delivers its result in the current SequenceReceiver of the XPathContext object.
