Swig: C++ to C#, adding addtional base classes

[Praveen Reddy]

Hello All



We are using SWIG to convert C++ code to C#

We need to add additional interfaces (base classes) in the C# code

By default the C# code generated is as follows



MyClass : IDisposable

{

}



Where MyClass is defined in the C++



We need something as shown blow:



MyClass : IDisposable, ICloneable

{

}



So we need the C# classes to have support additional interfaces (e.g.
ICloneable or custom interfaces)



Is it possible? If yes how can it be done?



Thanks and Regards

Praveen Reddy

Hi,

In java it is

%typemap(javainterfaces)

You can look at this doc 1.3:

21.9.9 Java code typemaps
http://www.swig.org/Doc1.3/SWIGDocumentation.html#java_code_typemaps


so you can use in C# that is very close

%typemap(csinterfaces) and there is another one look at 18.2 for that
18.2 Differences to the Java module

Hi Marouane



Thanks a lot - the following code in interface file helped me adding ICloneable as base class

%typemap(csbase) Shape "ICloneable"

%typemap(cscode) Shape %{

public object Clone()

{

return null;

}

%}



This raises another question. If the base class type is in other C# assembly - what would be the way to add reference to the SWIG project using the "interface file"?

%typemap(csbase) Shape "IMyInterface"



The definition of IMyInterface is present in other assembly.



Thks and Rgds

Praveen

Hi.

I suppose it is possible to use something like
%pragma(csharp) moduleimports=
%{
using System;
%}

or

%typemap(csimports) SWIGTYPE "using System;"
Hope that will help.

Regards,
Alex.
