Re: [HAPI-devel] Validation of HL7 message

[Bryan T. <bp...@gm...>]

Hi David,=20

I'm not sure this can be done with conformance profiles, unless you
are expecting a constant number of columns (e.g. always 4).

If you used HAPI 0.5, you could easily do this with a MessageRule. You
would implement ca.uhn.hl7v2.validation.MessageRule to check this
constraint and produce a ValidationException if it isn't met. You
would then have to tell your parser to apply this rule, using
Parser.setValidationContext(). The argument to this method is a
ca.uhn.hl7v2.validation.ValidationContext. See
ca.uhn.hl7v2.validation.impl.DefaultValidationContext for an example.
