public interface Option<T>
Options used for finer configuration. In contrast to dropwizard configuration file, which is user specific, options are set during development and represent developer decisions. Options must be grouped with enum (for example, seeGuiceyOptions
. Usage within enums does not allow using generics for option values checking, so option type set explicitly and used internally to validate option type on option value set.Options could be set only on application (root) level using
GuiceBundle.Builder.option(Enum, Object)
method, so all options are always set before bundles processing.Option may provide default value (useful for most cases, especially boolean options). Option may not be set to null (protected by implementation).
Option may be accessed in bundle using
GuiceyBootstrap.option(Enum)
method or usingOptions
guice bean. Installers could access options usingWithOptions
interface.Option reads and writes are tracked in order to detect useless and default value options. All tracked information is available through
OptionsInfo
