Using nested types

You are browsing legacy Javonet 1.5 (Java<>.NET bridge for Windows) documentation. Use the left side menu or click here to switch to latest Javonet 2.0 documentation. Javonet 2.0 allows you to use any module from JVM, CLR, Netcore, Python, Ruby, Perl, NodeJS on Windows, Linux and MacOs from any application created in Java, Clojure, Groovy, Kotlin, C#, F#, J#, VB.NET, Python, Perl, Ruby, JavaScript, TypeScript, C++ and GoLang

Nested types are the classes defined within other class or struct. Javonet is able to create the instance of nested type, pass nested type as Type argument, set nested type to field or property and use nested types as generic arguments for methods and classes.

More about nested types you can read in MSDN documentation: Nested Types

Assuming we have a custom .NET Framework DLL with the following classes inside:

using System;

namespace TestNamespace
{
	public class TestClass
	{
		public TestClass() { }
		~TestClass()
		{
			Console.WriteLine("Displaying object from .NET destructor message");
		}
		public static int MyStaticField { get; set; }
		public int MyInstanceField { get; set; }

		public static string SayHello(string name)
		{
			return "Hello " + name;
		}

		public int MultiplyByTwo(int arg)
		{
			return arg * 2;
		}

		public T MyGenericMethod<T>(T arg1)
		{
			return arg1;
		}
		public K MyGenericMethodWithTwoTypes<T, K>(T arg1)
		{
			return default(K);
		}

		public void MethodWithRefArg(ref int arg)
		{
			arg = arg + 44;
		}

		public string PassTypeArg(Type myType)
		{
			return myType.ToString();
		}

		public string MethodWithEnumArg(SampleEnum value)
		{
			return value.ToString();
		}
	}
}

And

namespace TestNamespace
{
	public class Container
	{
		public class Nested
		{
			public Nested() { }
		}
	}
}

To reference nested type with full namespace the name of the nested class should be prefixed with namespace, name of parent class and "+" sign. For example the "Nested" class defined above could be access using following path "TestNamespace.Container+Nested". Following examples show how to initialize and work with nested types using full namespace.
