Package io.inverno.mod.configuration

Interface ConfigurationLoader<A,B extends ConfigurationLoader<A,B>>

Type Parameters:

A - the configuration type

B - the configuration loader type

All Known Implementing Classes:

AbstractConfigurationLoader, BootConfigurationLoader, BootNetClientConfigurationLoader, BootNetServerConfigurationLoader, ConfigurationLoaderSupport, GrpcBaseConfigurationLoader, GrpcClientConfigurationLoader, GrpcServerConfigurationLoader, HttpClientConfigurationLoader, HttpServerConfigurationLoader, JOSEConfigurationLoader, LDAPClientConfigurationLoader, LettuceRedisClientConfigurationLoader, VertxSqlClientConfigurationLoader, WebServerConfigurationLoader

public interface ConfigurationLoader<A,B extends ConfigurationLoader<A,B>>

A configuration loader is used to load a configuration object from a ConfigurationSource.

A typical usage is:

 ConfigurationSource<?,?> source = ...

 SomeConfiguration configuration = ConfigurationLoader
     .withConfiguration(SomeConfiguration.class)
     .withParameters("environment", "test", "profile", "perf")
     .withSource(source)
     .load()
     .block();
 

Please refer to @Configuration documentation to learn how to define a proper configuration type.

Method Details

withConfiguration

static <E> ConfigurationLoader<E,?> withConfiguration(Class<E> configurationType)
                                               throws IllegalArgumentException

Creates a configuration loader to load configuration of the specified type.

Type Parameters:

E - the configuration type to load

Parameters:

configurationType - a class of type E

Returns:

a configuration loader

Throws:

IllegalArgumentException - if the specified type is not an interface

withConfigurator

static <E,
F> ConfigurationLoader<E,?> withConfigurator(Class<F> configuratorType,
 Function<Consumer<F>,E> configurationCreator)

Creates a configuration loader with a specified configurator type and configuration creation function.

The configurator is acting as a builder: it exposes single argument methods to set the values of configuration properties whose names are the name of the methods.

Then the creator builds the configuration from the configurator.

Unlike withConfiguration(Class), it is possible to load a configuration for any kind of object and not only interface since the creation of the configuration instance is delegated to the supplied configuration creator.

Type Parameters:

E - the configuration type to load

F - the configurator type

Parameters:

configuratorType - a class of type F

configurationCreator - a function that builds the configuration from the configurator

Returns:

a configuration loader
