com.thecoderscorner.menu.domain.MenuItem

com.thecoderscorner.menu.domain.AnalogMenuItem

public class AnalogMenuItem
extends MenuItem

Represents an analog (numeric) menu item, it is always a zero based integer when retrieved from storage, but it can have an offset and divisor, so therefore is able to represent decimal values. The offset can also be negative. Rather than directly constructing an item of this type, you can use the AnalogMenuItemBuilder.
