## Class ConfigViewImpl

- java.lang.Object
- - org.wildfly.swarm.container.config.ConfigViewImpl

- All Implemented Interfaces:
    ConfigView, StageConfig

      public class ConfigViewImpl
      extends Object
      implements ConfigView

  A view of merged/activated configurations.

  If an explicit properties object is provided (`withProperties(Properties)`, then the System properties will be completely ignored. If not, then System properties will be inspected, and any non-property based configuration will be reflect back into the live and active System properties.
