    initialize in class csw.framework.scaladsl.ComponentHandlers
  - jInitialize
```
public abstract void jInitialize()
```
    A Java helper that is invoked when the component is created. The component can initialize state such as configuration to be fetched from configuration service, location of components or services to be fetched from location service etc. These vary from component to component.

```
    The onShutdown handler can be used for carrying out the tasks which will allow the component to shutdown gracefully
  - onShutdown
```
public void onShutdown()
```
    Invokes the java helper (jOnShutdown) to shutdown the component
    Note: do not override this from java class
