Method Details

resolve

public URILocation resolve(String href,
                           String documentBase)
            throws URIException
Resolves the given href and documentBase. The href can either be an absolute or a relative URI as defined by IETF RFC 2396:
  • Absolute URI: [scheme]:'//'[authority][absolute path]
  • Relative URI: '//'[authority][absolute path] or [relative path] or [absolute path].

Note:

  1. When [authority] is not used then '//' must not be used.
  2. An [absolute path] begins by a '/' sign.
For instance the following URIs are valid:
        file:/c:/Program Files/MyApp/myresource.xml
        file://usr/etc/myresource.xml
        http://www.castor.org/index.html
        ../relative/index.html
    
However, the following won't be valid:
        file://c:/Program Files/MyApp/myresource.xml
    
Specified by:
resolve in interface URIResolver
Returns:
the URILocation for the URI

resolveURN

public URILocation resolveURN(String urn)
            throws URIException
Resolves the given urn. An implementation of this method may return null if the URN could not be resolved.
Specified by:
resolveURN in interface URIResolver
Returns:
the URILocation for the URN
