io.helidon.common.config.GlobalConfig
@Deprecated(forRemoval=true, since="4.2.0") public final class GlobalConfig extends Object
Deprecated, for removal: This API element is subject to removal in a future version.
Use Services.get(Class), or ServiceRegistry.get(Class) if you have an instance ready to obtain the "global" configuration; in case you are writing a registry service, simply inject the config instance; use Services.set(Class, Object[]) to use a custom instance of configuration, just make sure it is registered before it is used the first time
Global configuration can be set by a user before any Helidon code is invoked, to override default discovery of configuration done by Helidon components.

If method config(java.util.function.Supplier) is called before Helidon is started, Helidon will only use that configuration.

You may still use custom instances of configuration when using configurable APIs directly.
