Create a private getter to retrieve the current State

This method retrieves the State object representing the entity's current state. Note that the method is private, as the State object is not exposed outside of the entity - callers which require to know the entity's state must use getLifecycleState instead.

The relevant State object is retrieved by looking it up in the map of states.

/**
       * @return The State object representing the current state of
       *         this entity
       */
     private State<MYLIFECYCLEENTITYSTATEEntry> getState() {
      return states.get(getLifecycleState());
      }
