isDigit(char c)
|
(package private) static boolean |
isKeywordConstituent(char c)
We could use isAlpha, but as u see from the keyword table,
there appear only lower case words an tha characters '0' ad '1', so we
can shrink the number of tests. |
static void |
main(java.lang.String[] args)
|
(package private) void |
matchKeyword()
Checks whether there is a kwyword starting at tha current
point or not and sets the tokType accordingly. |
(package private) boolean |
noMoreTokens()
no more tears ! |
