How do I use Java Generics with Lookup?
NetBeans Master Developer FAQof NetBeans 6, a number of convenience methods have been added to lookup, and support for Java generics has been added to Lookup. The following are differences: Lookup.Template t = new Lookup.Template(X.class); Lookup.Result r = lkp.lookup(t); Collection c = r.allInstances(); The new style also works well with for-loops and avoids casts: for (SomeService s : Lookup.getDefault().lookupAll(SomeService.class)) { // ... } // ... SomeSingleton s = Lookup.getDefault().lookup(SomeSingleton.
Related QuestionsWhen Should I Use Generics?
Generics FAQ: FundamentalsYou should use generics whenever you have the option to. Meaning, if a data structure or a utility class offers a generic version, you should use the generic version, not the object-based methods. The reason is that generics offer significant benefits, including productivity, type safety and performance, at literally no cost to you.

Related QuestionsHow does the compiler translate Java generics?
Java Generics FAQs - Under The Hood Of The CompilerBy creating one unique byte code representation of each generic type (or method) and mapping all instantiations of the generic type (or method) to this unique representation. A compiler that must translate a generic type or method (in any language, not just Java) has in principle two choices: Code specialization. The compiler generates a new representation for every instantiation of a generic type or method.

Why Can't I Use Type-Specific Data Structures Instead of Generics?
Generics FAQ: FundamentalsTo avoid the type-safety problem without generics, you might be tempted to use type-specific interfaces and data structure, for example: public interface IIntegerList { int Add(int value); bool Contains(int value); int IndexOf(int value); void Insert(int index, int value); void Remove(int value); int this[int index]{ get; set; } //Additional members } Public Interface IIntegerList Function Add(ByVal value As Integer) As Integer Function Contains(ByVal value As Integer) As Boolean Function IndexO.

Ontario GenWebIf you're seeking an archive lookup, write to the archive itself. Include an SAE and 2 IRC's and keep your request short and simple. Some archives are very small and short-staffed so a nominal fee may be required.

Related QuestionsHow Are Generics Implemented?
Generics FAQ: FundamentalsGenerics have native support in IL and the CLR itself. When you compile generic server-side code, the compiler compiles it into IL, just like any other type. However, the IL only contains parameters or place holders for the actual specific types. In addition, the metadata of the generic server contains generic information such as constraints. The client-side compiler uses that generic metadata to support type safety.
Related QuestionsWhat's the problem with .NET generics?
Andy Mc's .NET Framework FAQNET generics work great for container classes. But what about other uses? Well, it turns out that .NET generics have a major limitation - they require the type parameter to be constrained. For example, you cannot do this: static class Disposer<T> { public static void Dispose(T obj) { obj.Dispose(); } } The C# compiler will refuse to compile this code, as the type T has not been constrained, and therefore only supports the methods of System.Object. Dispose is not a method on System.
