Method Detail

length

public int length(byte[] bytes,
                  int p,
                  int end)

Description copied from class: Encoding

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

Specified by:

length in class Encoding

Returns:

0 Never > 0 Valid character, length returned -1 Illegal/malformed character < -1 (-1 - n) Number of missing bytes for character in p...end range Oniguruma equivalent: mbc_enc_len modified for 1.9 purposes,

mbcToCode

                     int p,
                     int end)

Description copied from class: Encoding

Returns code point for a character Oniguruma equivalent: mbc_to_code

Specified by:

mbcToCode in class Encoding

codeToMbcLength

public int codeToMbcLength(int code)

Description copied from class: Encoding

Returns character length given a code point Oniguruma equivalent: code_to_mbclen

Specified by:
