java.lang.Object net.sf.saxon.tree.tiny.TinyTreeEventIterator
public class TinyTreeEventIterator
This implementation of the Saxon event-pull interface starts from a document, element,
text, comment, or processing-instruction node in a TinyTree,
and returns the events corresponding to that node and its descendants (including
their attributes and namespaces). The class performs the same function as
the general-purpose Decomposer
class, but is
specialized to exploit the TinyTree data structure: in particular, it never
materializes any Node objects.
