Interface ConfigMapperProvider

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ConfigMapperProvider

Provides ConfigMappers each of which converts a Config subtree to a specific Java type.

The config system automatically loads ConfigMapperProviders using the Java ServiceLoader mechanism, and by default the config system automatically registers all ConfigMappers from all such providers with every Config.Builder. The application can suppress auto-registration of loaded mappers by invoking Config.Builder.disableMapperServices().

Each ConfigMapperProvider can specify a Priority. The default priority is 100.
