A provider is a Coffig component type responsible for providing tree nodes that will be merged into the global configuration tree. A provider implements the org.seedstack.coffig.spi.ConfigurationProvider interface.

Programmatic registration

To register a provider programmatically, you create an instance of the provider and add it as a parameter to the withProviders() Coffig builder method:

Coffig.builder()
      .withProviders(new MyProvider())
      .build();

Declarative registration

You can also register an evaluator automatically by adding its fully qualified class name in META-INF/services/org.seedstack.coffig.spi.ConfigurationProvider:

org.myorg.myapp.MyProvider
