the defined COMMENT constant or -1

isValidIdentifierStart

protected boolean isValidIdentifierStart(char ch)
The default implementation of checkIdentifier will call this method to determine whether or not a particular character can be the start of an identifier.
Parameters:
ch - the char to be checked
Returns:
true if ch can be the start of an identifier
See Also:
AbstractScanner#checkIdentifier

isValidIdentifierPart

protected boolean isValidIdentifierPart(char ch)

Parameters:
ch - the char to be checked
Returns:
true if ch can be part of an identifier

isSymbol

protected boolean isSymbol(char ch)
The default implementation of checkSymbol will call this method to determine whether or not a particular character is a valid symbol.
Parameters:
ch - the char to be checked
