All Implemented Interfaces:

public class InterningXMLReader
extends org.xml.sax.helpers.XMLFilterImpl

XMLReader that interns all the string constants before calling the ContentHandler.

Most of the parsers out there (at least Crimson and Xerces) supports SAX http://xml.org/sax/features/string-interning feature, but if the parser doesn't support it (or if the SAX events is read from components other than XMLReader, this adaptor is used to make all strings interned.

JAXB RI 1.0.3
