Hex Validator
=============

``Zend\Validator\Hex`` allows you to validate if a given value contains only hexadecimal characters. These are all
characters from **0 to 9** and **A to F** case insensitive. There is no length limitation for the input you want to
validate.

.. code-block:: php
   :linenos:

   $validator = new Zend\Validator\Hex();
   if ($validator->isValid('123ABC')) {
       // value contains only hex chars
   } else {
       // false
   }

.. note::

   **Invalid characters**

   All other characters will return false, including whitespace and decimal point. Also unicode zeros and numbers
   from other scripts than latin will not be treated as valid.
