How to access Settings from InstancioServiceProvider.GeneratorProvider

[nstdio]

I've been writing org.instancio.spi.InstancioServiceProvider to use GeneratorProvider for generating objects which Instancio cannot create. I'd like to my GeneratorProvider configurable via Settings API, but it appears to me I'm missing something because I cannot access the Settings API easily, only by using internal API. Here's how I managed within org.instancio.spi.InstancioServiceProvider.GeneratorProvider#getGenerator:

    Settings result = null;
    if (generators.bytes() instanceof AbstractGenerator<?> gen) {
      result = gen.getContext().getSettings();
    }

This is quite dirty way to do it. Is there a conventional/supported way to access Settings API in this context?

This one is bit hidden. The supported way to access Settings is through InstancioServiceProvider.init(ServiceProviderContext) method. The ServiceProviderContext interface exposes getSettings() (and random() if you need it for generating reproducible data).

public class MyServiceProvider implements InstancioServiceProvider {

    private Settings settings;

    @Override
    public void init(ServiceProviderContext context) {
        this.settings = context.getSettings();
    }

    @Override
    public GeneratorProvider getGeneratorProvider() {
        return (node, generators) -> {
            // settings.get(...)
        };
    }
}

The init() method is called once getGeneratorProvider() runs, so it should never be null.
