public abstract class HexStringFormatAttribute
extends AbstractFormatAttribute

Base class for hexadecimal string-based representations

This class is particularly useful to validate hexadecimal-based string data. The only two constructor arguments you have to specify are a short description of the validated string and its expected length.

In this package, it is used for validating MD5, SHA1, SHA256 and SHA512 checksums, which are very commonly represented in form of hexadecimal strings of fixed length.
