Class Base64.Decoder

  • Enclosing class:
    Base64

    public abstract static class Base64.Decoder
    extends Object
    An encoder is an object, which is able to decode char arrays in blocks of four bytes. Any such block is converted into a array of three bytes.
    • Constructor Detail

      • Decoder

        protected Decoder​(int pBufLen)
        Creates a new instance.
        Parameters:
        pBufLen - The decoders buffer size. The decoder will store up to this number of decoded bytes before invoking writeBuffer(byte[],int,int).

      • writeBuffer

        protected abstract void writeBuffer​(byte[] pBuffer,
                                            int pOffset,
                                            int pLen)
                                     throws IOException
        Called for writing the decoded bytes to the destination.
        Parameters:
        pBuffer - The byte array being written.
        pOffset - Offset of the first byte being written.
        pLen - Number of bytes being written.
        Throws:
        IOException - Writing to the destination failed.
      • write

        public void write​(char[] pData,
                          int pOffset,
                          int pLen)
                   throws IOException
        Converts the Base64 encoded character array.
        Parameters:
        pData - The character array being decoded.
        pOffset - Offset of first character being decoded.
        pLen - Number of characters being decoded.
        Throws:
        Base64.DecodingException - Decoding failed.
        IOException - An invocation of the writeBuffer(byte[],int,int) method failed.
