public void registerContext(Identity idt,
                            java.net.URL url)
```
    This implementation accepts PluginDescriptor or PluginFragment as valid plug-in elements.
    
    Specified by:
    
    registerContext in interface PathResolver
    
    Parameters:
    
    idt - plug-in element
    
    url - "home" URL for a given plug-in element
    
    See Also:
    
    PathResolver.registerContext( org.java.plugin.registry.Identity, java.net.URL)
  - unregisterContext
```
public void unregisterContext(java.lang.String id)
```
    Description copied from interface: PathResolver
    
    Unregisters plug-in element from this path resolver.
    
    Specified by:
    
    unregisterContext in interface PathResolver
    
    Parameters:
    
    id - plug-in element identifier
    
    See Also:
    
    PathResolver.unregisterContext(java.lang.String)
  - resolvePath
```
public java.net.URL resolvePath(Identity identity,
                                java.lang.String path)
```
    Description copied from interface: PathResolver
    
    Should resolve given path to URL for a given identity.
    
    Specified by:
    
    resolvePath in interface PathResolver
    
    Parameters:
    
    identity - plug-in element for which to resolve path
    
    path - path to be resolved
    
    Returns:
    
    resolved absolute URL
    
    See Also:
    
    PathResolver.resolvePath( org.java.plugin.registry.Identity, java.lang.String)
  - getRegisteredContext
```
public java.net.URL getRegisteredContext(java.lang.String id)
```
    Description copied from interface: PathResolver
    
    Returns URL of registered plug-in element context. If context for plug-in element with given ID not registered, this method should throw an IllegalArgumentException. In other words, this method shouldn't return null.
    
    Specified by:
    
    getRegisteredContext in interface PathResolver
    
    Parameters:
    
    id - plug-in element identifier
    
    Returns:
    
    registered context "home" location

    PathResolver.getRegisteredContext(java.lang.String)
  - isContextRegistered
```
public boolean isContextRegistered(java.lang.String id)
```
    Specified by:
    
    isContextRegistered in interface PathResolver
    
    Parameters:
    
    id - plug-in element identifier
    
    Returns:
    
    true if context for plug-in element with given ID registered
    
    See Also:
    
    PathResolver.isContextRegistered(java.lang.String)
  - resolvePath
```
protected java.net.URL resolvePath(java.net.URL baseUrl,
                                   java.lang.String path)
```
    Resolves given path against given base URL.
    
    Parameters:
