Method Details

validateAuthentication

protected T validateAuthentication(T authentication)

The authentication method to be implmented by sip authentication providers. By default it just calls the token validator, and if the token is valid, the same token is returned with the isAuthenticated flag set to true. Otherwise the token from the argument is returned as it was.

If necessary this method can be overridden to provide a more sophisticated validation logic.

Parameters:

authentication - the token which should be checked for proper authentication

Returns:

a token which is either authenticated or not (can be the same as the input)
