I am trying Antlr v3 for message recognition, which must comply to a custom
define protocol.
I find myself unable to express the following rule (written in a
non-standard notation):
data: count number{count.value}
What I am expecting to find in the input is a numerical value (which Ive
labeled count), followed by as many numerical values as the value of count.
Examples of valid input:
3 10 12 15
2 6 9
Examples of invalid input:
3 10 12
2 4 5 6
This seems like a trivial message protocol situation, so I'm hoping this is
a solved problem.
Ive gone through The Definitive Antlr Reference, and can't find information
on quantifiers that would help me solve this issue.
Ideas? guidance?
Thanks very much in advance.
