[QUESTION] How to cast an internal member variable type?

[softempire]

Hi There,

I have a class
class A
{
public:
int data;
}

enum EType
{
TypeA = 0,
TypeB
}

I want to expose data as EType, how can I do this? Does pybind have a cast function?

def_readwrite("data", &A::data) will return an int value.

I can define a property
def_property("data",
[](A& inst)
{
return static_cast(inst.data);
},
[](A& inst, EType newData)
{
inst.data = static_cast(newData);
}

but it looks not good enough.

I know I can change the type for data to EType. But if the class is written by other people and I can't change it.

I found we can use (EType A::*)(&A::data). It works
