SAXParser (Java 2 Platform SE 5.0) (original) (raw)

javax.xml.parsers

Class SAXParser

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

public abstract class SAXParser

extends Object

Defines the API that wraps an XMLReader implementation class. In JAXP 1.0, this class wrapped theParser 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 theSAXParserFactory.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 theDefaultHandler are called.

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

SAXParser

protected SAXParser()

Protected constructor to prevent instaniation. Use SAXParserFactory.newSAXParser().

reset

public void reset()

Reset this SAXParser to its original configuration.

SAXParser is reset to the same state as when it was created withSAXParserFactory.newSAXParser().reset() is designed to allow the reuse of existing SAXParsers thus saving resources associated with the creation of new SAXParsers.

The reset SAXParser is not guaranteed to have the same Schema Object, e.g. Object.equals(Object obj). It is guaranteed to have a functionally equalSchema.

parse

public void parse(InputStream is, HandlerBase hb) throws SAXException, IOException

hb - The SAX HandlerBase to use.

Throws:

[IllegalArgumentException](../../../java/lang/IllegalArgumentException.html "class in java.lang") - If the given InputStream is null.

[SAXException](../../../org/xml/sax/SAXException.html "class in org.xml.sax") - If parse produces a SAX error.
