Method Detail

getCharsetName

public String getCharsetName()

Description copied from class: Encoding

The name of the equivalent Java Charset for this encoding. Defaults to the name of the encoding. Subclasses can override this to provide a different name.

Overrides:

getCharsetName in class Encoding

Returns:

the name of the equivalent Java Charset for this encoding

mbcCaseFold

public int mbcCaseFold(int flag,
                       byte[] bytes,
                       IntHolder pp,

                       byte[] lower)

iso_*_mbc_case_fold

Parameters:

flag - case fold flag

pp - an IntHolder that points at character head

lower - a buffer where to extract case folded character Oniguruma equivalent: mbc_case_fold

isCodeCType

Overrides:

isCodeCType in class CaseFoldMapEncoding

Parameters:

code - a code point of a character

ctype - a character type to check against Oniguruma equivalent: is_code_ctype
