int |
codeToMbc(int code,
byte[] bytes,
int p)
Extracts code point into it's multibyte representation
|
int |
codeToMbcLength(int code)
Returns character length given a code point
Oniguruma equivalent:
code_to_mbclen |
int[] |
ctypeCodeRange(int ctype,
IntHolder sbOut)
Returns code range for a given character type
Oniguruma equivalent:
get_ctype_code_range |
java.lang.String |
getCharsetName() |
boolean |
isCodeCType(int code,
int ctype)
Perform a check whether given code is of given character type (e.g.
|
boolean |
isReverseMatchAllowed(byte[] bytes,
int p,
int end)
Returns true if it's safe to use reversal Boyer-Moore search fail fast algorithm
Oniguruma equivalent:
is_allowed_reverse_match |
int |
leftAdjustCharHead(byte[] bytes,
int p,
int s,
int end)
Seeks the previous character head in a stream
Oniguruma equivalent:
left_adjust_char_head |
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 |
