int |
getChannel() |
int |
getCharPositionInLine()
The index of the first character relative to the beginning of the line 0..n-1
|
CharStream |
getInputStream()
From what character stream was this token created? You don't have to
implement but it's nice to know where a Token comes from if you have
include files etc...
|

String |
getText()
Get the text of the token
|
int |
getTokenIndex()
An index from 0..n-1 of the token object in the input stream.
