A processor is a Coffig component type responsible for processing and mutating the global configuration tree (after provider merging). A processor implements the org.seedstack.coffig.spi.ConfigurationProcessor interface.

Programmatic registration

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

Coffig.builder()
      .withProcessors(new MyProcessor())
      .build();

Declarative registration

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

org.myorg.myapp.MyProcessor
