Method Detail

encode

int encode(CharSequence in,
         OutputStream out)

Encode a Unicode character sequence. The run length of the encoded sequence is NOT marked in the output.

Parameters:

in - The Unicode data.

out - Where to write the encoded data.

Returns:

The #of bytes written onto the output stream

decode

int decode(InputStream in,
         Appendable out)

Decode a Unicode character sequence from the input stream. The run length of the encoded sequence is NOT marked in the input, so the caller must provide a view consisting of exactly the bytes to be decoded.

Parameters:

in - The encoded data.

out - The decoded data (Unicode characters) are appended to this object.

Returns:

The #of bytes that were consumed.
