Brontekst bekijken van Bench with subobjects

[[Bestand:Bench.png|right|thumb|220px|Sample bench]]This page shows how to use the Coins-api.dll and cbim.dll for creating a [[CoinsCore:ContainsRelation Class|Coins Contains Relation]].

This sample uses the same bench as in the previous sample. In this example the bench contains of three subobjects:
* support-left
* support-right
* beam


We have to tell the bench that it is both an Object and an Assembly. We call this Multi-Typing. Therefore, you can use the method addType.
 bench.addType(typeof(Assembly));

Multiple typed objects can be cast to the preferred type in order to have access to functions/methods belonging to this type. The next code snippet casts a Bench object to an Assembly.<br>
 Assembly benchAsAssembly = (Assembly)bench.@as(typeof(Assembly));

Below, the relations has been programmed for the support-left only. This support-left is both an object and a part. Via the ContainsRelation the bench and the support-left are connected to each other.:

 // Start container
 JenaModelFactory factory = new JenaModelFactory();
 JenaCoinsContainer ccr = new JenaCoinsContainer(factory, "http://demo.nl#");
 
 // Create individual
 nl.coinsweb.cbim.Object bench = new nl.coinsweb.cbim.Object(ccr);
 nl.coinsweb.cbim.Object supportLeft = new nl.coinsweb.cbim.Object(ccr);
 ContainsRelation crel = new ContainsRelation(ccr);
 
 // Individual with multiple types
 bench.addType(typeof(Assembly));
 Assembly benchAsAssembly = (Assembly)bench.@as(typeof(Assembly));
 supportLeft.addType(typeof(Part));
 
 // Configure ContainsRelation
 crel.setHasPart((Part)supportLeft.@as(typeof(Part)));
 benchAsAssembly.addHasContainsRelation(crel);  
    
 // Set property
 bench.setName("Couch");
 supportLeft.setName("Support Left Side");
 
 // Export container
 ccr.export("D:\\assembly.ccr");

All Coins objects that are put into a Coins Container, must be typed CoinsContainerObject.
Therefore, this line of code is needed: <br>
 ccr.batchAddCoinsContainerObjectType()
