    • Field Summary

      Fields 
      Modifier and Type Field Description
      private static byte[] altBase64ToInt
      This array is the analogue of base64ToInt, but for the nonstandard variant that avoids the use of uppercase alphabetic characters.
      private static byte[] base64ToInt
      This array is a lookup table that translates unicode characters drawn from the "SVNBase64 Alphabet" (as specified in Table 1 of RFC 2045) into their 6-bit positive integer equivalents.

        private static final char[] intToAltBase64

      • base64ToInt

        private static final byte[] base64ToInt
        This array is a lookup table that translates unicode characters drawn from the "SVNBase64 Alphabet" (as specified in Table 1 of RFC 2045) into their 6-bit positive integer equivalents. Characters that are not in the SVNBase64 alphabet but fall within the bounds of the array are translated to -1.

      • altBase64ToInt

        private static final byte[] altBase64ToInt
        This array is the analogue of base64ToInt, but for the nonstandard variant that avoids the use of uppercase alphabetic characters.
