Class Options

java.lang.Object

ru.vyarus.dropwizard.guice.module.context.option.Options

public final class Options
extends java.lang.Object

Guice bean for accessing options from guice services. Bean usage is equivalent of option method for guicey bundle.

Also used by installers to access options (see WithOptions).

IMPORTANT: In contrast to OptionsInfo (which must be used for reporting only), this bean must be used for real option value usage. Only this bean will correctly return default value for option not used before (no set no gets).
