JSON string To Class Object

[ghost]

Expected behavior

I Have a class named CDemo , it contains some data members , and i got a json string to represent a CDemo object , could i use CDemo o = v.convert(); if so ,it will be much easier for use , so
i dont need to write a lot of getValue to extract the value to the CDemo object.
i read the source code , as if this can be done for suppling a VarHolderImpl
template <>
class VarHolderImpl : public VarHolder
{
...
};

Actual behavior

I want to confirm is that can be done.

Can be done, yes. Look at JSON::Object or Dynamic::Struct, it would be something similar. Obviously, there's some "wrapping" and many idle member functions (not applicable data types, but must be provided) with Dynamic::Var but, given everything, it performs quite well, especially if you know upfront the type inside and use extract<T>() to avoid type conversions.

I had read the code ,but it's a little difficult to me , so can someone make a sample for me ?
To illustrate , the class could make a little complex , it may contains a vector or map of some objects.

Dynamic::Struct<int> ms_int;
Dynamic::Var ms_var = ms_int;

//ok
auto ms_str_other = ms_var.extract<Dynamic::Struct<string>>();

//error
auto ms_int_other = ms_var.extract<Dynamic::Struct<int>>();

Could this error be ok?
