Yeah pretty cool! It automatically strips the common prefix if it's the same as
the enum name. And you can use annotations in the java code to verify that you
only assign values from the enum set, but didn't seem worth it. e.g., you'd
declare it as: @CipherModeEnum int cipherMode;

   enum CipherMode {
     CIPHER_MODE_UNENCRYPTED,
     CIPHER_MODE_AES_CTR,
     CIPHER_MODE_AES_CBC,
     CIPHER_MODE_MAX = CIPHER_MODE_AES_CBC
   };
 
   // CENC 3rd Edition adds pattern encryption, through two new protection
   // schemes: 'cens' (with AES-CTR) and 'cbcs' (with AES-CBC).
   // The pattern applies independently to each 'encrypted' part of the frame (as
