As per part 4 of my last comment, in my most recent commit I've allowed
`FormatWriterFactory` and `DelegatingWriterFactory` to extend the same
(package-private) base interface specifying a single generic method:
```java
interface BaseWriterFactory<Output> extends WriterFactory {
TripleHandler getTripleWriter(Output o);
}
```
I could have added this method directly to `WriterFactory` (with a default
implementation of throwing `UnsupportedOperationException`), but since all
instances of this interface *must* be instances of either `FormatWriterFactory`
or `DelegatingWriterFactory` (since the interface is package-private), and all
interaction with this method will be done by casting to one of these two
interfaces, adding generic arguments to `WriterFactory` itself would have only
added unnecessary verbosity (e.g., always having to specify `WriterFactory<?>`
instead of `WriterFactory` to avoid rawtypes warnings).
@lewismc any comments?
