/**
* Provides the ability to store energy on the implementing item.
*
* This interface is a special version of IElectricItem which delegates the implementation of
* charge(), discharge() and canUse() to the implementing Item.
*
* The default implementation (when not using ICustomElectricItem) does the following:
* - store and retrieve the charge
* - handle charging, taking amount, tier, transfer limit, canProvideEnergy and simulate into account
2013-04-13 16:35:13 +02:00
* - replace item IDs if appropriate (getChargedItemId() and getEmptyItemId())
* - update and manage the damage value for the visual charge indicator
*
* @note ICustomElectricItem must not call the ElectricItem methods charge, discharge or canUse
*
* @deprecated Use ISpecialElectricItem instead.
