Class GlobalConfig

java.lang.Object
io.helidon.common.config.GlobalConfig
public final class GlobalConfig extends Object
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.
