Defining Children

You can create children which are similar to attributes with two distinctions:

  • Their types can only be KML concepts.
  • The link between an object and its Children is stronger than the link to an attribute: children are aggregated by their father KML objects. Thus, every KML object has an "Owner" attribute pointing to its father Object.

Before you begin: You have created a concept called MyTable of BaseConcept type.

Defining an Attribute
  1. In the Know-how Apps Logic Editor, key in the following script: 
    Children
         {
             /* A table is made up of a Top and a Foot... Whose Reference is instantiated 4 times! */
             MyTableTop tableTop;
             MyTableFoot tableFoot; 
             /* The table is also made up of constraints used to position the feet instances.*/
             /*  The Constraint concepts are defined in the SampleTools library. */
             List(KMLCoincidenceConstraint) tableConstraints;
         }
