There's a builder pattern than works. It's a little ugly but it's what

I'd call that "factory pattern". Why did you pick "builder"?
Kind regards

They're similar. I've seen the term "builder" used more often when the
construction is done by the implementor and "factory" more often when
the construction is performed by a single system. Builder also has a
pattern of SomeThing a= new
Builder().with(Options.B).add(x).add(y).addAll(Z).makeImmutable(); It's
a way to specify arguments after construction without allowing access to
a partially built object.
I would say the difference is that a builder is a type of factory which
can be configured before the factory method is invoked.
