public final class SAXImpl

extends SAX2DTM2

implements DOM, DOMBuilder

SAXImpl is the core model for SAX input source. SAXImpl objects are usually created from an XSLTCDTMManager.

DOMSource inputs are handled using DOM2SAX + SAXImpl. SAXImpl has a few specific fields (e.g. _node2Ids, _document) to keep DOM-related information. They are used when the processing behavior between DOM and SAX has to be different. Examples of these include id function and unparsed entity.

SAXImpl extends SAX2DTM2 instead of SAX2DTM for better performance.
