Adding a Requirement in a Collection

Once you have instantiated an OSLC client, you can use the UpdateCollection class to add (or remove) a requirement in a DOORS Next Collection.

The first step is to access the existing content of a DOORS Next Collection. At this stage it is critical to keep track of the ETag part of the response. This ETag is to reference in the update request, so that DOORS Next can ensure the collection was not modified by another user meanwhile.

	OslcClient client = OslcClients.jazzForm(new UsernamePasswordCredentials("myUser", "myPassword")).create();
	
	// get the existing requirement
	URI collectionUri = URI.create("https://myServer:9443/rm/myCollection");
	ResourceResponse<DngCollection> response = new GetCollection(client, collectionUri).call();
	DngCollection collection = response.getEntity();
	String eTag = response.getETag();
	
	// add a reference to an existing requirement
	Collection<URI> requirements = Arrays.asList(collection.getUses());
	requirements.add(URI.create("https://myServer:9443/rm/myRequirement"));
	collection.setUses(requirements.toArray(new URI[requirements.size()]));
	
	// send the update to the server
	new UpdateCollection(client, collectionUri, eTag, collection).call();
