Class AbstractStaxContentHandler

java.lang.Object
  org.springframework.util.xml.AbstractStaxContentHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler

Direct Known Subclasses:

StaxEventContentHandler, StaxStreamContentHandler

abstract class AbstractStaxContentHandler
extends java.lang.Object
implements org.xml.sax.ContentHandler

Abstract base class for SAX ContentHandler implementations that use StAX as a basis. All methods delegate to internal template methods, capable of throwing a XMLStreamException. Additionally, an namespace context is used to keep track of declared namespaces.

Since:

3.0
