Class ResourceResolver

java.lang.Object

org.apache.xml.security.utils.resolver.ResourceResolver

public class ResourceResolver
extends java.lang.Object

During reference validation, we have to retrieve resources from somewhere. This is done by retrieving a Resolver. The resolver needs two arguments: The URI in which the link to the new resource is defined and the BaseURI of the file/entity in which the URI occurs (the BaseURI is the same as the SystemId.

• Verschiedene Implementierungen k??nnen sich als Resolver registrieren.
• Standardm????ig werden erste Implementierungen auf dem XML config file registrirt.
• Der Benutzer kann bei Bedarf Implementierungen voranstellen oder anf??gen.
• Implementierungen k??nnen mittels Features customized werden ?? (z.B. um Proxy-Passworter ??bergeben zu k??nnen).
• Jede Implementierung bekommt das URI Attribut und den Base URI ??bergeben und muss antworten, ob sie aufl??sen kann.
• Die erste Implementierung, die die Aufgabe erf??llt, f??hrt die Aufl??sung durch.
