22 * The Abstract Integer class defines implementation of IntegerTypeDefinition
23 * interface which represents UNSIGNED Integer values defined in Yang language. <br>
24 * The integer built-in types in Yang are uint8, uint16, uint32, and uint64.
25 * They represent unsigned integers of different sizes:
28 * <li>uint8 - represents integer values between 0 and 255, inclusively.</li>
29 * <li>uint16 - represents integer values between 0 and 65535, inclusively.</li>
30 * <li>uint32 - represents integer values between 0 and 4294967295, inclusively.
32 * <li>uint64 - represents integer values between 0 and 18446744073709551615,
