Enum Class ByteSizeUnit
- All Implemented Interfaces:
Serializable
,Comparable<ByteSizeUnit>
,Constable
,Writeable
A
SizeUnit
represents size at a given unit of
granularity and provides utility methods to convert across units.
A SizeUnit
does not maintain size information, but only
helps organize and use size representations that may be maintained
separately across various contexts.-
