Examples of ModuleStateHolder

org.impalaframework.module.ModuleStateHolder
The main job of the `ModuleStateHolder` is to maintain information on the state of modules loaded. This includes references to the {@link ApplicationContext}s which back the modules, as well as to currently loaded {@link ModuleDefinition}s. It also exposes a few convenience methods for querying the state of the module hierarchy. @author Phil Zoio
