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

All Implemented Interfaces:

org.xml.sax.EntityResolver
```
public class DTDResolver
extends java.lang.Object
implements org.xml.sax.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.
