java.lang.Object
  sk.uniba.euromath.gene.builtin.PrefixMappingTracker

All Implemented Interfaces:

ContentHandler

public class PrefixMappingTracker
extends Object
implements ContentHandler

Pipes the events through itself to another content handler. Tracks the namespace - prefix mapping for all namespaces occured, and ensures that startDocument() and endDocument() are never called.
