Package com.saxonica.ee.stream.watch Description

This package contains defines the two interfaces Watch and WatchMaker, and various implementations of these interfaces.

A Watch is used on a streaming pipeline to recognize specific events, such as the start of a selected element, and to take action when these events occur. A WatchMaker is a factory class for creating a particular kind of Watch. The WatchManager is a class that sits on the Receiver pipeline keeping track of which Watches are active, and notifying them of events so that they can decide whether they are of interest.
