Method Summary

Modifier and TypeMethod and Description
public int
codeToMbc(int code, byte[] bytes, int p)

Implements abstract org.jcodings.Encoding.codeToMbc.

Extracts code point into it's multibyte representation
public int
codeToMbcLength(int code)

Implements abstract org.jcodings.Encoding.codeToMbcLength.

Returns character length given a code point Oniguruma equivalent: code_to_mbclen
public int[]
ctypeCodeRange(int ctype, IntHolder sbOut)

Implements abstract org.jcodings.Encoding.ctypeCodeRange.

Returns code range for a given character type Oniguruma equivalent: get_ctype_code_range
public boolean
isCodeCType(int
a code point of a character
code, int
a character type to check against Oniguruma equivalent: is_code_ctype
ctype)

Implements abstract org.jcodings.Encoding.isCodeCType.

Perform a check whether given code is of given character type (e.g. used by isWord(someByte) and similar methods)
protected boolean
isLead(int c)

Implements abstract org.jcodings.EucEncoding.isLead.

public boolean
isReverseMatchAllowed(byte[] bytes, int p, int end)

Implements abstract org.jcodings.Encoding.isReverseMatchAllowed.

Returns true if it's safe to use reversal Boyer-Moore search fail fast algorithm Oniguruma equivalent: is_allowed_reverse_match
public int
length(byte[] bytes, int p, int end)

Implements abstract org.jcodings.Encoding.length.

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
public int
mbcCaseFold(int
case fold flag
flag, byte[] bytes, IntHolder
an IntHolder that points at character head
pp, int end, byte[]
a buffer where to extract case folded character Oniguruma equivalent: mbc_case_fold
lower)

Overrides org.jcodings.AbstractEncoding.mbcCaseFold.

onigenc_ascii_mbc_case_fold
public int
mbcToCode(byte[] bytes, int p, int end)

Implements abstract org.jcodings.Encoding.mbcToCode.
