Bench with subobjects

Sample bench

This page shows how to use the Coins-api.dll and cbim.dll for creating a 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.

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:

ccr.batchAddCoinsContainerObjectType()
