Oggetto: [Boost-users] [program_options][1.35] validating string value
A:
Hi,
My option (say, "opt1") can take any of only few possible string type values
(say, "value1", "value2", "value3" and "value4"). Is there anyway to specify
this such that if any other value, say - "valueXX", is passed to "opt1", it
throws an error?
If yes, can someone point me to documentation or sample code snippet to show
how to do this?
Or, explicitly, checking against these possible values is my only option?
Regards,
~ Soumen
