javapackage typemap, but SWIG doesn't generate the right JNI field
descriptor.</i>
<p>
Use the template's renamed name as the argument to the "javapackage" typemap:
Provide the package name in a "javapackage" typemap for the type:
</p>
<div class="code">
<pre>
%typemap(javapackage) std::vector&lt;int&gt; "your.package.here"
%typemap(javapackage) std::vector&lt;int&gt; "com.funky"
%template(VectorOfInt) std::vector&lt;int&gt;;
%feature("director") MyDirector;
struct MyDirector {
virtual ~MyDirector();
virtual void takeVector(std::vector<int> vec);
};
</pre>
</div>
<p>
The descriptor <tt>com/funky/VectorOfInt</tt> for <tt>VectorOfInt</tt> in the generated code
will then be derived from the provided package "com.funky". Below shows the relevant snippet of generated code
with the full descriptor:
</p>
<div class="code">
<pre>
SwigDirectorMethod(jenv, baseclass, "takeVector", "(Lcom/funky/VectorOfInt;)V")
</pre>
</div>
</li>
