Suppress parameter from module class method

I've got the following swig file:

%module test

%ignore Stats;
%typemap(jstype)    Stats*  ""
%typemap(javain)    Stats*  "0"
 
void initialize(Stats* s);

I would like to suppress the 'Stats* s' parameter from the module class and just pass '0' to the JNI function

public class test {
  public static void initialize( s) { // How to supppress this parameter ?
    testJNI.initialize(0);
  }

}

I could not get rid of the parameter of the initialize method. Do you know what is the correct typemaps?

I read something about javaparams, but could not any documentation about it, and does not seems to work, or I do not use it correctly.
