public class StAXPropertyHandler
extends StAXContentHandlerBase

StAX handler shamelessly ripped off from Thomas Down's XFFFeatureSetHandler. NOTE This class is not thread-safe -- it must only be used for one parse at any time. This class is the basis for classes that do not create a new feature but modify an existing feature. It is not compulsory for property handlers to subclass this class but those that don't but wish to use the handler stack facility need to use the StaxFeatureHandler's push and pop methods.

Since:
1.8
