Class ComplexNodeEventFeed
java.lang.Object
com.saxonica.stream.feed.EventFeed
com.saxonica.stream.feed.ComplexNodeEventFeed
- All Implemented Interfaces:
- Feed
public class ComplexNodeEventFeed
- extends EventFeed
This event feed supports instructions that create a document or element node. The events
representing the start and end of the element or document are written to the destination
receiver during the open() and close() calls. Between these two calls, the child instruction
representing the content of the document or element pushes its output to the same destination
receiver.
The instruction-dependent code is contained in the processLeft() and processRight() methods
of the expression object, which must be a DivisibleInstruction

open
public void open()
throws XPathException
- Description copied from class:
EventFeed
- Start evaluating the expression. This must call open() on the parent expression
feed before it does anything else. For the default implementation, this is all that
it does. Note that it does not open the destination receiver.
