Class SAXParser

java.lang.Object
javax.xml.parsers.SAXParser

Direct Known Subclasses:

JXSAXParser

public abstract class SAXParser

extends java.lang.Object

Defines the API that wraps an org.xml.sax.XMLReader implementation class. In JAXP 1.0, this class wrapped the org.xml.sax.Parser interface, however this interface was replaced by the XMLReader. For ease of transition, this class continues to support the same name and interface as well as supporting new methods. An instance of this class can be obtained from the SAXParserFactory.newSAXParser method. Once an instance of this class is obtained, XML can be parsed from a variety of input sources. These input sources are InputStreams, Files, URLs, and SAX InputSources.

This static method creates a new factory instance based on a system property setting or uses the platform default if no property has been defined.

The system property that controls which Factory implementation to create is named "javax.xml.parsers.SAXParserFactory". This property names a class that is a concrete subclass of this abstract class. If no property is defined, a platform default will be used.

As the content is parsed by the underlying parser, methods of the given HandlerBase or the DefaultHandler are called.

Implementors of this class which wrap an underlaying implementation can consider using the org.xml.sax.helpers.ParserAdapter class to initially adapt their SAX1 impelemntation to work under this revised class.

Since:

JAXP 1.0
