Template Parameters:

R – return value type

Public Functions

inline R operator()()#
template<typename R>
FunctionHandler<PyFunctionHandler<R>> YR::PyFunction(const std::string &moduleName, const std::string &functionName)#

Used for C++ to call Python functions, constructs a call to a Python function. 

int main(void)
{
    // def add_one(a):
    //     return a + 1
    YR::Config conf;
    YR::Init(conf);

    auto r1 = YR::PyFunction<int>("pycallee", "add_one").Invoke(x);  // moduleName, functionName
    auto res = *YR::Get(r1);

    std::cout << "PlusOneWithPyFunc with result=" << res << std::endl;
    return res;

    return 0;
}

Template Parameters:

R – The return type of the function.

Parameters:

  • moduleName – The name of the Python module where the function resides.

  • functionName – The name of the Python function.

Returns:

A FunctionHandler object, which provides methods to execute the function. The PyFunctionHandler is a template class within FunctionHandler that can be used to obtain the return type.
