EntityResolver

EntityResolver

org.xml.sax

---

Java 1.4

An application can implement this interface to help the parser resolve external entities, if required. If you pass an EntityResolver instance to the setEntityResolver( ) method of an XMLReader , then the parser will call the resolveEntity( ) method whenever it needs to read an external entity. This method should use the public identifier or system identifier to return an InputSource that the parser can use to read the content of the external entity. If the external entity includes a valid system identifier, then the parser can read it directly without the need for an EntityResolver , but this interface is still useful for mapping network URLs to locally cached copies, or for mapping public identifiers to local files, for example. The helper class org.xml.sax.helpers.DefaultHandler includes a stub implementation of this interface, so if you subclass DefaultHandler you can override its resolveEntity( ) method.

 public interface  EntityResolver  {  // Public Instance Methods  InputSource  resolveEntity  (String  publicId  , String  systemId  )          throws SAXException, java.io.IOException;   }
