All Implemented Interfaces:

Feed

public class ForkingFeed
extends EventFeed

Watch for an xsl:fork instruction. This doesn't really need to be a Watch, because it always processes the context node; but it means we can reuse a lot of code from the ApplyTemplatesWatch

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.

Specified by:

open in interface Feed

Overrides:

open in class EventFeed

Throws:

XPathException - to report any failure
