boolean	isCodeCType(int code, int ctype)	ascii_is_code_ctype / ONIGENC_IS_ASCII_CODE_CTYPE
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
byte[]	toLowerCaseTable()	Returns lower case table if it's safe to use it directly, otherwise null Used for fast case insensitive matching for some singlebyte encodings

length

public int length(byte[] bytes,
                  int p,
                  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

Overrides:

length in class SingleByteEncoding

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,

toLowerCaseTable

public final byte[] toLowerCaseTable()

Description copied from class: Encoding

Returns lower case table if it's safe to use it directly, otherwise null Used for fast case insensitive matching for some singlebyte encodings

Overrides:

toLowerCaseTable in class Encoding

Returns:

lower case table

getCharsetName

public java.lang.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

isCodeCType

public boolean isCodeCType(int code,
                           int ctype)

ascii_is_code_ctype / ONIGENC_IS_ASCII_CODE_CTYPE

Specified by:

isCodeCType in class Encoding

Parameters:

code - a code point of a character

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