JOB keys are created by JOB key maps and are immutable objects. They are returned by method JobKeyMap.put(Object) on a key map instance. JOB keys are dependent on JOB key maps and keep a reference to these. The owning key map of a JOB key is returned by method
public JobKeyMap getMap()
You can retrieve a JOB key's value calling method
public Object get()
This method delegates to the owning key map. It is intended for navigation.
