- Method Detail
  - name
```
String name()
```
    The name of the kernel is determined with its
    
    Returns:
    
    the name of the Kernel.
  - init
```
void init()
```
    Tell the kernel to initialize. The kernel will load all the plugins and initialize them.
    Plugins will the create an intermediate UnitModule.
  - isInitialized
```
boolean isInitialized()
```
    Indication on whether or not the kernel is initialized.
    
    Returns:
    
    true if the kernel is initialized.
  - plugins
```
Map<String,Plugin> plugins()
```
    After the kernel is initialized, if necessary, one can ask for the map of plugins.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Returns:
    
    map of plugins organized by name
  - unitModule
```
UnitModule unitModule(Class<? extends Plugin> plugin)
```
    After the kernel is initialized, one can ask for the particular UnitModule created by one plugin.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Parameters:
    
    plugin - this is the plugin from which we want the UnitModule.
    
    Returns:
    
    the unitModule
  - overridingUnitModule
```
UnitModule overridingUnitModule(Class<? extends Plugin> plugin)
```
    After the kernel is initialized, one can ask for the particular Overriding UnitModule created by one plugin.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Parameters:
    
    plugin - this is the plugin from which we want the UnitModule.
    
    Returns:
    
    the unitModule
  - nonGuiceUnitModule
```
UnitModule nonGuiceUnitModule(Class<? extends Plugin> plugin)
```
    After the kernel is initialized, one can ask for the particular UnitModule created by one plugin.
    Some times the plugin can return a native module that is not a Guice Module (the internal used D.I. engine).
    Non Guice Module are handled via DependencyInjectionProvider.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Parameters:
    
    plugin - this is the plugin from which we want the UnitModule.
    
    Returns:
    
    the unitModule
  - nonGuiceOverridingUnitModule
```
UnitModule nonGuiceOverridingUnitModule(Class<? extends Plugin> plugin)
```
    After the kernel is initialized, one can ask for the particular Overriding UnitModule created by one plugin.
    Some time the plugin can return a native module that is not a Guice Module (the internal used D.I. engine).
    Non Guice Module are handled via DependencyInjectionProvider.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Parameters:
    
    plugin - this is the plugin from which we want the UnitModule.
    
    Returns:
    
    the unitModule
  - globalModule
```
GlobalModule globalModule()
```
    After the kernel is initialized, if necessary, one can ask for the global Module the result of all plugins UnitModule aggregation.
    This will rarely be the case. We advise developers to be careful with plugins.
    
    Returns:
    
    the global binding definition provider for all the application.
  - start
```
void start()
```
    Tell the kernel to start. Then the kernel will create the ObjectGraph of the application. The ObjectGraph will wrap the actual Guice injector.
    The injector is created by combining nominal global modules and global modules to override.
  - isStarted
```
boolean isStarted()
```
    Indication on whether or not the kernel is started.
    
    Returns:
    
    true if the kernel is started.
  - objectGraph
```
ObjectGraph objectGraph()
```
    After the kernel is started, one can ask the ObjectGraph generated from the global module itself generated by all the modules the plugins create.
    
    Returns:
    
    the ObjectGraph
  - stop
```
void stop()
```
    This methods will stop all the plugins in the reverse order of the started plugins.
