Returns:boolean

true if the given range was extended

getCodeLengthback to summary
public int getCodeLength()

Returns the byte length of the codes of the CID range.

Returns:int

the code length

mapback to summary
public int map(byte[] bytes)

Maps the given Unicode character to the corresponding CID in this range.

Parameters
bytes:byte[]

Unicode character

Returns:int

corresponding CID, or -1 if the character is out of range

mapback to summary
public int map(int code, int length)

Maps the given Unicode character to the corresponding CID in this range.

Parameters
code:int

Unicode character

length:int

origin byte length of the code
