java.lang.Object
- com.javonet.api.NNull

```
public class NNull
extends java.lang.Object
```
A class that represents type specific NULL value.

This class should be used in case when ambiguous invocation error occurs. Or when you want to pass as value null of specific .NET type.

Ambiguous invocation error can occur if there is more then one method on .NET side with the same method name and the same number of class type parameters and you want to invoce one of them passing null values as parameters. In this case .NET is not able to determine which method to invoce unless type-specific NULL is provided.

Usage

On .NET side
```
  MethodA(ClassA arg1, ClassB arg2)
 MethodB(ClassC arg1, ClassD arg2); 
 
```
How to invoke MethodA passing null values as parameters from JAVA using Javonet type-specific NULL value:
```
  obj.MethodA(new NNull("ClassA"),new NNull("ClassB")); 
 
```
.NET equivalent:
```
  obj.MethodA((ClassA)null,(ClassB)null); 
 
```
