Maybe little faster, especially for short strings:
private CoderResult decodeArrayLoop(ByteBuffer src, CharBuffer
dst) {
byte[] sa = src.array();
int sp = src.arrayOffset() + src.position();
int sr = src.remaining(); // faster than ...
src.arrayOffset() + src.limit()
char[] da = dst.array();
int dp = dst.arrayOffset() + dst.position();
int dr = dst.remaining(); // dl is never used
for (int sl = sp + (sr <= dr ? sr : dr); sp < sl; sp++, dp++)
if ((da[dp] = decode(sa[sp])) == UNMAPPABLE_DECODING)
return withResult(CoderResult.unmappableForLength(1),
src, sp, dst, dp);
return withResult(sr <= dr ? CoderResult.UNDERFLOW :
CoderResult.OVERFLOW, src, sp, dst, dp);
}
