Method Detail

except

public Grammar.CharacterSet except(int... codePoints)

set

public void set(String set)

Sets the name or definition of the set to base these characters on. The set can either be the name of a well-known unicode set (such as "ID_Start"), or it can be a set of characters in unicode set notation.

The set of well-known unicode set names are defined in the Unicode enum, in addition to those "EOI" or "EOF" are also accepted and means a "character" representing the end of the input stream.

Unicode set notation needs to be enclosed within [ and ] and needs to be a sequence of either:

• A single character, or
• a range of character, denoted as two characters with a dash (-) in between.

Parameters:

set - The set to base these characters on.
