ConfigModifier (dropwizard-guicey 6.3.1 API)

Type Parameters:

C - configuration type

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 ConfigModifier<C extends io.dropwizard.core.Configuration>
```
Configuration modifier is an alternative for configuration override, which is limited for simple property types (for example, a collection could not be overridden).
Modifier is called before application run phase. Only logger configuration is applied at this moment (and so you can't change it). Modifier would work with both yaml and instance-based configurations.
Could be declared in: - ExtensionBuilder.configModifiers( ConfigModifier[]) extension builder (same for dropwizard extension) - TestGuiceyApp.configModifiers() extension annotation (same for dropwizard annotation) - TestSupport.build(Class) - generic test support object builder - TestSupport.buildCommandRunner(Class) - generic test command runner - GuiceyTestSupport.configModifiers(ConfigModifier[]) - guicey support object (directly) - CommandTestSupport.configModifiers(ConfigModifier[]) - command support object (directly)
To enable support for DropwizardTestSupport custom command factory must be used: ConfigOverrideUtils.buildCommandFactory(java.util.List).
