themselves are stored in
_quadBuffer ). |

Flag that indicates that the current token has not yet
been fully processed, and needs to be finished for
some access (or skipped to obtain the next token)
|
protected static int |
STATE_HEADER
State for recognized header marker, either in-feed or initial.
|
