  - link
```
public void link(URI originUri,
        URI targetUri)
```
    Description copied from interface: KeyManager
    
    Notifies this key manager that a protected resource has been linked.
    
    Parameters:
    originUri - the origin URI of the protected resource.
    targetUri - the target URI of the protected resource.
  - provider
```
public KeyProvider<Object> provider(URI uri)
```
    Description copied from interface: KeyManager
    
    Returns a key provider for accessing the identified protected resource.
    
    Parameters:
    uri - the URI of the protected resource.
    
    Returns:
    a consistent (but not necessarily always the same) key provider for accessing the identified protected resource.
  - release
```
public void release(URI uri)
```
    Description copied from interface: KeyManager
    
    Notifies this key manager that a protected resource has been released. Clients should call this method only if they wish to reset or dispose the key provider which may be associated with the protected resource. Implementations may completely ignore this call or chose to reset or dispose the associated key provider based on its state. For example, an implementation may reset the key provider only if the user had cancelled the prompting for the key.
    
    Parameters:
    uri - the URI of the protected resource.
  - unlink
```
public void unlink(URI uri)
```
    Description copied from interface: KeyManager
    
    Notifies this key manager that a protected resource has been unlinked. This implies a KeyManager.release(java.net.URI).
    
    Parameters:
    uri - the URI of the protected resource.
