int |
leftAdjustCharHead(byte[] bytes,
int p,
int s,
int end)
Seeks the previous character head in a stream

int |
length(byte c)
Returns character length given character head
returns
1 for singlebyte encodings or performs direct length table lookup for multibyte ones. |
int |
length(byte[] bytes,
int p,
int end)
Returns character length given stream, character position and stream end
returns
1 for singlebyte encodings or performs sanity validations for multibyte ones
and returns the character length, missing characters in the stream otherwise |
