mandatory occurrences in ADL Parser

Reference Implementation: Java (archive)
1

Hi,

In using the ADL Parser, I just want to be sure I got this right:

CComplexObject myNode = <get a node within a parsed archetype from somewhere>;
Interval<Integer> myOccurrences = myNode.getOccurrences();

Now, if the occurrence is mandatory (1..1), myOccurrences will be null as mandatory is the default. For easier handling I therefore want to set the following in my code before proceeding:

if (myOccurrence == null) myOccurrence = new Interval<Integer>(1,1);
  
This should be semantically exactly the same I believe?

Regards
Sebastian

Hi Sebastian,

Actually it’s the CObject from AOM in question. The current code needs to be updated to make “occurrences” attribute mandatory according to the latest AOM specs from 1.0.1 release. When “occurrences” is not mentioned in ADL, the default one is {1..1}. So the solution you described is correct.

Cheers,
