SWIG supports type aliasing.

The following is an example of an alias template:
<div class="code"><pre>
template&lt; typename T1, typename T2, int &gt;
template&lt; typename T1, typename T2, int N &gt;
class SomeType {
public:
T1 a;
T2 b;

These are partially supported as SWIG will parse these and identify them, however, they are ignored as they are not added to the type system. A warning such as the following is issued:
SWIG supports both type aliasing and alias templates.
However, in order to use an alias template, the <tt>%template</tt> directive must be used:

<div class="shell">
<pre>
example.i:13: Warning 342: The 'using' keyword in template aliasing is not fully supported yet.

%template() TypedefName&lt;bool&gt;;
