Python ¶

The C++ code used for the examples below can be found here , and it is assumed that that code is loaded at the start of any session. Download it, save it under the name features.h , and load it:

>>> import cppyy
>>> cppyy.include('features.h')
>>>

PyObject ¶

Arguments and return types of PyObject* can be used, and passed on to CPython API calls (or through cpyext in PyPy).

Doc strings ¶

The documentation string of a method or function contains the C++ arguments and return types of all overloads of that name, as applicable. Example:

>>> from cppyy.gbl import Concrete
>>> print Concrete.array_method.__doc__
void Concrete::array_method(int* ad, int size)
void Concrete::array_method(double* ad, int size)
>>>

帮助 ¶

Bound C++ class is first-class Python and can thus be inspected like any Python objects can. For example, we can ask for help() :

>>> help(Concrete)
Help on class Concrete in module gbl:
class Concrete(Abstract)
 |  Method resolution order:
 |      Concrete
 |      Abstract
 |      CPPInstance
 |      __builtin__.object
 |
 |  Methods defined here:
 |
 |  __assign__(self, const Concrete&)
 |      Concrete& Concrete::operator=(const Concrete&)
 |
 |  __init__(self, *args)
 |      Concrete::Concrete(int n = 42)
 |      Concrete::Concrete(const Concrete&)
 |
 etc. ....
