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.

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

1.4

Constructor Details

SAXParser

protected SAXParser()

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

Method Details

reset

public void reset()

Reset this SAXParser to its original configuration.

SAXParser is reset to the same state as when it was created with SAXParserFactory.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 equal Schema.

Throws:

UnsupportedOperationException - When Implementations do not override this method

parse

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

Parse the content of the given InputStream instance as XML using the specified HandlerBase. Use of the DefaultHandler version of this method is recommended as the HandlerBase class has been deprecated in SAX 2.0.

Parameters:

is - InputStream containing the content to be parsed.

hb - The SAX HandlerBase to use.

Throws:

IllegalArgumentException - If the given InputStream is null.

SAXException - If parse produces a SAX error.

IOException - If an IO error occurs interacting with the InputStream.

parse

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

Parse the content of the given InputStream instance as XML using the specified HandlerBase. Use of the DefaultHandler version of this method is recommended as the HandlerBase class has been deprecated in SAX 2.0.

Parameters:

is - InputStream containing the content to be parsed.

hb - The SAX HandlerBase to use.

systemId - The systemId which is needed for resolving relative URIs.

Throws:

IllegalArgumentException - If the given InputStream is null.

IOException - If any IO error occurs interacting with the InputStream.

SAXException - If any SAX errors occur during processing.

• version of this method instead.
