This attribute can be applied to non-static "virtual data members" in a class or structure definition. The compiler treats these "virtual data members" as data members by changing their references into function calls.
__declspec( property( get=get_func_name ) ) declarator __declspec( property( put=put_func_name ) ) declarator __declspec( property( get=get_func_name, put=put_func_name ) ) declarator
When the compiler sees a data member declared with this attribute on the right of a member-selection operator ("." or "->"), it converts the operation to a get or put function, depending on whether such an expression is an l-value or an r-value. In more complicated contexts, such as "+=", a rewrite is performed by doing both get and put.
This attribute can also be used in the declaration of an empty array in a class or structure definition. For example:
__declspec(property(get=GetX, put=PutX)) int x;
The above statement indicates that
x can be used with one or more array indices. In this case,
i=p->x[a][b] will be turned into
i=p->GetX(a, b), and
p->x[a][b] = i will be turned into
p->PutX(a, b, i);
