public abstract class ConfigurationLoaderSupport<A,B,C extends ConfigurationLoaderSupport<A,B,C>>
extends AbstractConfigurationLoader<A,C>

Base implementation for generated configuration loader.

ConfigurationLoaderSupport implementations are generated by the Inverno configuration compiler and loads configuration properties explicitly invoking generated configurator and builder to eventually load the configuration.

This configuration loader works as follows:

If a configuration source is specified:

1. Loads a list of properties from the configuration source
2. Maps the resulting query results to a configurer whose role is to inject the appropriate property values in a configurator specific to the configuration to load
3. Invokes a configuration creator which uses the previous configurator to create the configuration

If no configuration is specified, fallback to a default configuration supplier to create the configuration.

Since:

1.0

resultsToConfigurer - a mapper function that maps the configuration query results to a configurer

configurationCreator - a configuration creator

defaultConfigurationSupplier - a default configuration supplier

Method Details

withConfigurer

public C withConfigurer(Consumer<B> configurer)

Sets a configurer that will override the configurer supplied when creating the loader when loading the configuration.

Parameters:

configurer - a configurer

Returns:

the configuration loader

load

public Mono<A> load()

Description copied from interface: ConfigurationLoader

Loads the configuration from the configuration source with the specified parameters.

Returns:

a mono emitting the resulting configuration object
