Dean Moldovan b4498ef44d Add py::isinstance<T>(obj) for generalized Python type checking ... Allows checking the Python types before creating an object instead of after. For example: ```c++ auto l = list(ptr, true); if (l.check()) // ... ``` The above is replaced with: ```c++ if (isinstance<list>(ptr)) { auto l = reinterpret_borrow(ptr); // ... } ``` This deprecates `py::object::check()`. `py::isinstance()` covers the same use case, but it can also check for user-defined types: ```c++ class Pet { ... }; py::class_<Pet>(...); m.def("is_pet", [](py::object obj) { return py::isinstance<Pet>(obj); // works as expected }); ```		2016-11-17 08:55:42 +01:00
