Detailed Description

All wrapper classes inherit from Wrapper. Native open62541 objects can be accessed using the Wrapper::handle() member function.

Wrapper types are pointer-interconvertible to the wrapped native type and vice versa:

Use asWrapper(NativeType*) to cast native object pointers to wrapper object pointers.
Use asWrapper(NativeType&) to cast native object references to wrapper object references.
Use asNative(WrapperType*) to cast wrapper object pointers to native object pointers.
Use asNative(WrapperType&) to cast wrapper object references to native object references.

According to the standard:

‍Two objects a and b are pointer-interconvertible if: One is a standard-layout class object [wrapper] and the other is the first non-static data member of that object [wrapped native type]. Derived classes must fulfill the requirements of standard-layout types to be convertible.
