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 the 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.

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 underlying implementation can consider using the ParserAdapter class to initially adapt their SAX1 impelemntation to work under this revised class.

An implementation of SAXParser is NOT guaranteed to behave as per the specification if it is used concurrently by two or more threads. It is recommended to have one instance of the SAXParser per thread or it is upto the application to make sure about the use of SAXParser from more than one thread.

Since:

JAXP 1.0

Method Detail

parse

public void parse(InputStream is,

hb - The SAX HandlerBase to use.

Throws:

IOException - If any IO errors occur.

IllegalArgumentException - If the given InputStream is null.

SAXException - If the underlying parser throws a SAXException while parsing.
