- Method Detail
  - getItemRating
```
public int getItemRating()
```
    Returns an item value for ComputerFigures rating in the items category.
    
    Overrides:
    
    getItemRating in class Item
    
    Returns:
    
    energy * 10.
  - getShieldPower
```
public int getShieldPower()

    Returns the shields power (which is same as duration). Per default, ItemShielding calculates the Shield power by energy/energyFactor, so subclasses might adjust the energyfactor for linear energy - shield power behaviour, or override getShieldPower.
    
    Returns:
    
    The gain.
  - calculateDuration
```
protected int calculateDuration()
```
    Calculates the duration.

protected void doSpecialUpdate(AnimationInfo animation)
```
    Performs the update in each round in overridden classes. Recalculates duration.
    
    Overrides:
    
    doSpecialUpdate in class ItemPermanent
    
    Parameters:
    
    animation - The AnimationInfo
