    • decode

      public void decode(CharBuffer input, ByteBuffer output) throws EncodingException
      Description copied from interface: Decoder
      Decodes characters in input buffer into bytes placed in the output buffer. This method may be called multiple times, followed by Decoder.finalize(ByteBuffer). after all input bytes have been provided.
      Specified by:
      decode in interface Decoder
      Parameters:
      input - Input character buffer.
      output - Output byte buffer.
      Throws:
      EncodingException - on decoding errors.
    • finalize

      public void finalize(ByteBuffer output) throws EncodingException
      Description copied from interface: Decoder
      Performs final output decoding (e.g. padding) after all input characters have been provided.
      Specified by:
      finalize in interface Decoder
      Parameters:
      output - Output byte buffer.
      Throws:
      EncodingException - on decoding errors.
    • outputSize

      public int outputSize(int inputSize)
      Description copied from interface: Decoder
      Expected number of bytes in the output buffer for an input buffer of the given size.
      Specified by:
      outputSize in interface Decoder
      Parameters:
      inputSize - Size of input buffer in characters.
      Returns:
      Minimum byte buffer size required to store all decoded characters in input buffer.
