Method Details

length

public int length(byte c)

onigenc_single_byte_mbc_enc_len

Specified by:

length in class Encoding

Parameters:

c - Character head Oniguruma equivalent: mbc_enc_len To be deprecated very soon (use length(byte[]bytes, int p, int end) version)

length

public int length(byte[] bytes,

 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,
