public final class IntegerWithUnitConfigAttribute
extends ConfigAttribute

This class defines a configuration attribute that stores both an integer value and an associated unit. The unit will contain both a string and a floating-point value. When a unit is selected, then the associated value will be used as a multiplier for the integer value to achieve the actual value for this parameter. For example, the attribute could be used to specify a size in bytes, but a value with a unit of "kb" could multiply that value by 1024, or "mb" by 1048576, or "gb" by 1073741824. In this case, a value of "50 gb" would be the logical equivalent of "53687091200 b". Upper and lower bounds may be imposed, and in that case they will be imposed on the actual value not on merely the integer portion. This attribute may only hold a single value and it will always be required.
