How to programmatically make use of the OptionalPlaceHolder

[AGO]

Hello,
I am currently trying to build up a dynamic information model. The aim is to read in an XML file with import() and map the data to the information model. There are elements in the XML file which can occur 0, 1 or unbounded times. I modelled them as Optional Placeholder. Now I want to dynamically decide based on the occurance of an element in the XML how many optional placeholders should be instantiated during the call of import().
How can I instantiate the Object2 in Code?

Object1 (ObjectyType1, Mandatory)
-Variable1 (Mandatory)
-Variable2 (Mandatory)
-Object2 (ObjectType2, Optional Placeholder)
--Variable3
--Variable4
--Object3(ObjectType3, OptionalPlaceholder)
...

I managed to instantiate Optionals dynamically with the setVariable(x)-method, but the Optional Placeholder instantiation seems to be more complicated.

Thank you very much in advance.

Hello,

you need to create an instance of ObjectType2 and call addObject2().

Code: Select all

NodeManager *pNM;
ObjectType1 *pObject1 = new ObjectType1(nodeId1, name1, nsIdx, pNM);
pNM->addNodeAndReference(parentNodeId, pObject1 , referenceTypeId)
ObjectType2 *pObject2 = new ObjectType2(nodeId,2 name2, nsIdx, pNM);
pObject1->addObject2(pObject2);
