Method

CharBuffer bytesToChars(CharsetDecoder decoder, ByteBuffer bytes, CharBuffer chars)
Convert byte buffer's content into characters.

assert decoder.malformedInputAction() == CodingErrorAction.REPORT;
chars = clearAndEnsureCapacity(chars, (int) (bytes.remaining() * decoder.maxCharsPerByte()));
bytes.mark();
decoder.reset();
CoderResult cr = decoder.decode(bytes, chars, true);
if (cr.isError()) {
 bytes.reset();
