Method Summary

Modifier and TypeMethod and Description
public int
caseMap(IntHolder flagP, byte[] bytes, IntHolder pp, int end, byte[] to, int toP, int toEnd)

Implements abstract org.jcodings.Encoding.caseMap.

Oniguruma equivalent: case_map
public static boolean
isInRange(int code, int from, int to)

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

Implements abstract org.jcodings.Encoding.length.

Returns character length given character head returns 1 for singlebyte encodings or performs direct length table lookup for multibyte ones.
