+--org.apache.xerces.util.ObjectFactory
- public class ObjectFactory
- extends java.lang.Object
This class is duplicated for each JAXP subpackage so keep it in sync.
It is package private and therefore is not exposed as part of the JAXP
API.
This code is designed to implement the JAXP 1.1 spec pluggability
feature and is designed to both compile and run on JDK version 1.1 and
later. The code also runs both as part of an unbundled jar file and
when bundled as part of the JDK.
This class was moved from the javax.xml.parsers.FactoryFinder
class and modified to be used as a general utility for creating objects
dynamically.
