Interface PathHandler

All Known Implementing Classes:
AbstractSVGNormPathSegList.NormalizedPathSegListBuilder, AbstractSVGPathSegList.PathSegListBuilder, AWTPathProducer, DefaultPathHandler, PathArrayProducer

public interface PathHandler

This interface must be implemented and then registred as the handler of a PathParser instance in order to be notified of parsing events.
