Interface ConfigBeanProxy

All Known Subinterfaces:

VersionedConfigBeanProxy

@Customizer(value=ConfigBeanProxyCustomizer.class)
public interface ConfigBeanProxy

Marker interface that signifies that the interface is meant to be used as a strongly-typed proxy to Dom.

To obtain the Dom object, use Dom.unwrap(ConfigBeanProxy). This design allows the interfaces to be implemented by other code outside DOM more easily.
