/**

* This interface specifies a manager to handle the various tasks for electric items.
|
|
*
|
|
* The default implementation does the following:
|
|
* - store and retrieve the charge
|
|
* - handle charging, taking amount, tier, transfer limit, canProvideEnergy and simulate into account
|
|
* - replace item IDs if appropriate (getChargedItemId() and getEmptyItemId())
|
|
* - update and manage the damage value for the visual charge indicator
|
|
*
|
|
* @note If you're implementing your own variant (ISpecialElectricItem), you can delegate to the
|
|
* default implementations through ElectricItem.rawManager. The default implementation is designed
|
|
* to minimize its dependency on its own constraints/structure and delegates most work back to the
|
|
* more atomic features in the gateway manager.
