/**
|
* 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.
