Renders the specified model into a stream of code models. This is used
internally to provide the other interface methods.
<p>
If the specified transform is not installed, an empty stream will be
returned.

@param <A>        the input type
@param <B>        the expected output type
@param from       the model to generate
@param to         the model type to transform to
@param transform  the specified transform to use
@return           a stream of meta objects
