Class DTDResolver

java.lang.Object
  org.exolab.castor.util.DTDResolver

All Implemented Interfaces:

EntityResolver

public class DTDResolver
extends Object
implements EntityResolver

Entity resolver for various DTD/schema. Holds information and performs resolving on a variety of DTD and schema, both those defined by Castor and those used by Castor and cached by it.

The following DTD and XML schema are supported:

• Castor mapping DTD/Schema
• Castor JDO configuration DTD/Schema
• XML Schema DTDs

This resolver can resolve both public and system identifiers, and will return an input stream into a cached resource in the Castor JAR.

This resolver can be used as wrapper to another entity resolver. For example, if a resolver is used for external entities in the mapping file, construct a new resolver using the DTDResolver(EntityResolver) constructor.
