isValidDecimal
public boolean isValidDecimal()
Verify whether current token is a valid decimal token (which contains dot). Returns true if the character that follows the token is not a digit or letter or underscore. For example: For char stream "2.3", "2." is not a valid decimal token, because it is followed by digit '3'. For char stream "2.3_", "2.3" is not a valid decimal token, because it is followed by '_'. For char stream "2.3W", "2.3" is not a valid decimal token, because it is followed by 'W'. For char stream "12.0D 34.E2+0.12 " 12.0D is a valid decimal token because it is followed by a space. 34.E2 is a valid decimal token because it is followed by symbol '+' which is not a digit or letter or underscore.
-
isHint
public boolean isHint()
This method will be called when we see '/*' and try to match it as a bracketed comment. If the next character is '+', it should be parsed as hint later, and we cannot match it as a bracketed comment. Returns true if the next character is '+'.
