Interface ConfigSeeder

public interface ConfigSeeder

API used to seed a Config into a specific layer of the root CompositeConfig. Multiple ConfigSeeders may be bound for each layer and are invoked when the main Config is constructed. For example, the following code

 Multibinder.newSetBinder(binder(), ConfigSeeder.class, RuntimeLayer.class)
            .addBinding().toInstance(new ConfigSeeder() {
                public Config get(Config mainConfig) {
                    return MapConfig.from(props));
                }
             });
 

will load properties from 'prop' into the RuntimeLayer. Note that get(Config) receives the root configuration as a parameter. This enables the seeder to set properties based on the current state of the root composite config. Note that ConfigSeeders are invoked in the order in which they are bound.
