The following example outlines how to reference the sub-resources of a resource. In this example, a disk with the name 'my disk' that belongs to a virtual machine with the name 'test' is referenced.
Declare an instance of the resource whose sub-resources are to be referenced:
VM vm = api.getVMs().get("test");
Declare an instance of the sub-resource to be referenced:
VMDisk disk = vm.getDisks().get("my disk");
