How to read field type from boost property tree

Question

I use boost property trees to read values ​​from a json file.

{
    "some_values":
    {
        "field_1":  "value_1",
        "field_2":  true
    }
}

I can read the values ​​with:

spTree->get<string>("some_values.field_1",  "");
spTree->get<bool>("some_values.field_2",    false);

But can I read the type of the variable stored in any given field?
