Unions in Swig

[hemanth]

Hi

I am required to build a stub to access C API's from Java. For that
purpose I have used Swig to generate the wrapper code.

One of my structures contain "union" as a field. Now the generated
wrapper provides a get() method to access the union in Java, but there
is no set() method to assign a value. Can anybody suggest me about a
workaround either using Swig or in plain Jni.. Thanks in advance..


Thanks

If you are going to manipulate it from java you will need two setter
methods , as if the fields were disjoint, and you will need a getter
method to tell you with version is in there. If you don't have them
in C, you will need to write them.
