Interface ExternalSubsetResolver

All Superinterfaces:
org.apache.xerces.xni.parser.XMLEntityResolver
All Known Implementing Classes:
EntityResolver2Wrapper

public interface ExternalSubsetResolver
extends org.apache.xerces.xni.parser.XMLEntityResolver

This interface extends XMLEntityResolver providing a method to resolve external subsets for documents which do not explicitly provide one. The application can register an object that implements this interface with the parser configuration. If registered, it will be queried to locate an external subset when none is provided, even for documents that do not contain DOCTYPE declarations. If the registered external subset resolver does not provide an external subset for a given document, it should return null.
