Member Function Documentation

template<typename T>

static int ndarray::detail::PyConverterBase< T >::fromPython ( PyObject *  arg, T *  output  )

inlinestatic

Convert a Python object to a C++ object.

fromPython() is appropriate for use with the PyArg_ParseX Python C-API functions as a "O&" converter function.

Returns

true if the conversion was successful, and false otherwise (with a Python exception set).

Definition at line 98 of file PyConverter.h.

      {
        PyPtr p(arg,true);
        if (!PyConverter<T>::fromPythonStage1(p)) return false;
        return PyConverter<T>::fromPythonStage2(arg,*output);
    }

template<typename T>

static bool ndarray::detail::PyConverterBase< T >::matches ( PyObject *  arg )

inlinestatic

Check if a Python object might be convertible to T.

Returns

true if the conversion may be successful, and false if it definitely is not. Will not raise a Python exception.

This is mostly useful for wrapper generators like SWIG or Boost.Python, which could use matches() to check if an Python arguments match a particular signature for an overloaded C++ function.
