Method Details

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 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
