For example, the following methods can all be located in the same class: void DoWork() įor more information, see the C# Language Specification. Generic methods can be overloaded on several type parameters. void SwapIfGreater(ref T lhs, ref T rhs) where T : System.IComparable This version of Swap, now named SwapIfGreater, can only be used with type arguments that implement IComparable. withConnection Cannot resolve overloaded method 'withConnection' .DB (2.4.3) class / Execute a block of code, providing a JDBC connection.

Use constraints to enable more specialized operations on type parameters in methods. If you require the flexibility of calling a generic class method with type arguments other than the ones provided when the class was instantiated, consider providing another identifier for the type parameter of the method, as shown in GenericList2 in the following example. If you define a generic method that takes the same type parameters as the containing class, the compiler generates warning CS0693 because within the method scope, the argument supplied for the inner T hides the argument supplied for the outer T. Within a generic class, non-generic methods can access the class-level type parameters, as follows: class SampleClass In the overload resolution step, the compiler includes only those generic methods on which type inference succeeded. The compiler applies type inference logic to all generic methods that share the same name. Type inference occurs at compile time before the compiler tries to resolve overloaded method signatures. Therefore type inference does not work with methods that have no parameters. Now you can successfully check out from VCS, create, or import Scala projects.

The compiler can infer the type parameters based on the method arguments you pass in it cannot infer the type parameters only from a constraint or return value. To install Scala plugin, press Ctrl+Alt+S, open the Plugins page, browse repositories to locate the Scala plugin, click Install and restart IntelliJ IDEA. The same rules for type inference apply to static methods and instance methods. The following call to Swap is equivalent to the previous call: Swap(ref a, ref b) You can also omit the type argument and the compiler will infer it.

The following code example shows one way to call the method by using int for the type argument: public static void TestSwap() A generic method is a method that is declared with type parameters, as follows: static void Swap(ref T lhs, ref T rhs)
