These three functiosn can be used to query the state later. Done means that a call to Process will immediately return 1 Error if Process threw an exception last Ok if everything looks good (Process never been called, or last return 0 or possibly -1)

Attempt to parse some actions. At least one ParserActions should be on the action stack.
Run is not guaranteed to be recursively callable from inside a ParserActions callback. Do not do that.
return 0 on success return 1 when done return -1 if needing more data is detected (not all parsers support this; can be treated as an error) throw on error
