Examples of org.apache.xerces.impl.xs.XMLSchemaLoader

org.apache.xerces.impl.xs.XMLSchemaLoader
This class implements XMLGrammarLoader. It is designed to interact either with a proxy for a user application which wants to preparse schemas, or with our own Schema validator. It is hoped that none of these "external" classes will therefore need to communicate directly with XSDHandler in future.
This class only knows how to make XSDHandler do its thing. The caller must ensure that all its properties (schemaLocation, JAXPSchemaSource etc.) have been properly set. @author Neil Graham, IBM @version $Id: XMLSchemaLoader.java,v 1.12 2002/11/11 20:47:31 neilg Exp $
