It looks like that we are talking about 2 different interfaces. One is
the mmci interface and the other is the end-user interface. The end-user
interface is the decorator for the mmci interface. As a decorator the
end-user interface implements the mmci interface, but it can extend it
with extra functionality. The mmci stays a lightweight implementation
and the end-user is a skin around it.
interface CloudInterface {
getRelatedNodes(NodeManager n);
getNodeManager(String name);
}
class BasicCloud implements CloudInterface {
getRelatedNodes(NodeManager n) {
// some lightweight stuff
}
getNodeManager(String name) {
// some lightweight stuff
}
}
class Cloud implements CloudInterface {
CloudInterface cloud
getRelatedNodes(NodeManager n) {
cloud.getRelatedNodes(n);
}
getNodeManager(String name) {
cloud.getNodeManager(name);
}
getRelatedNodes(String name) {
NodeManager n = getNodeManager(name);
getRelatedNodes(n);
}
}
