Class ParserFactory

public class ParserFactory extends Object

Deprecated: This class works with the deprecated Parser interface.

Java-specific class for dynamically loading SAX parsers.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.

Note: This class is designed to work with the now-deprecated SAX1 Parser class. SAX2 applications should use XMLReaderFactory instead.

ParserFactory is not part of the platform-independent definition of SAX; it is an additional convenience class designed specifically for Java XML application writers. SAX applications can use the static methods in this class to allocate a SAX parser dynamically at run-time based either on the value of the `org.xml.sax.parser' system property or on a string containing the class name.

Note that the application still requires an XML parser that implements SAX1.

Note that this is not the ParserFactory shipped with SAX 2.0.1; this class takes into account the needs of J2EE 1.4 AccessControllers.

Since: SAX 1.0

Version: 2.0.1 (sax2r2)
