(2) The SWIG_NewPointerObj() call automatically wraps the exception object
into a shadow class. The SWIGTYPE_p_FullError is the type-descriptor
used for type checking. The "1" indicates that Python will have
ownership of the resulting object.
(3) The PyErr_SetObject call sets the Python exception. However,
the SWIGTYPE_p_FullError->clientdata reference may not be
obvious. This is actually the Python shadow class object
for FullError. Recall that in Python, exceptions are defined
as classes. Therefore, this works perfectly as the argument to

This example tests the SWIG run-time libraries and use of the
%import directive to work with multiple modules.
Use 'python runme.py' to run a test.
Overview:
---------
The example defines 4 different extension modules--each wrapping
a separate C++ class.
base.i - Base class
foo.i - Foo class derived from Base
bar.i - Bar class derived from Base
spam.i - Spam class derived from Bar
Each module used %import to refer to another module. For
example, the 'foo.i' module uses '%import base.i' to get
definitions for its base class.
If everything is working correctly, all of the modules will load
correctly and type checking will work correctly. The
example requires the use of the SWIG run-time libraries
which must be built and properly installed.

This example tests the SWIG run-time libraries and use of the
%import directive to work with multiple modules. However,
unlike the import example, this uses templates to really
stress test the type-system.
Use 'python runme.py' to run a test.
Overview:
---------
The example defines 4 different extension modules--each wrapping
a separate C++ class.
base.i - Base class
foo.i - Foo class derived from Base
bar.i - Bar class derived from Base
spam.i - Spam class derived from Bar
Each module used %import to refer to another module. For
example, the 'foo.i' module uses '%import base.i' to get
definitions for its base class.
If everything is working correctly, all of the modules will load
correctly and type checking will work correctly. The
example requires the use of the SWIG run-time libraries
which must be built and properly installed.
