Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

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;
