Class SchemaLocator

  SchemaLocator

All Implemented Interfaces:

XSDSchemaLocator

public class SchemaLocator
extends Object
implements XSDSchemaLocator

Helper class which ensures that the xsd schema parser uses pre-build schema objects.

This class works from a XSD which contains a reference to the schema.

Example usage:

         XSD xsd = ...;
         String namespaceURI = xsd.getNamesapceURI();

         SchemaLocator locator = new SchemaLocator( xsd );
         XSDSchema schema = locator.locateSchema( null, namespaceURI, null, null);
