Documentation

The template class PP_CpClassPtr<T> is derived from PP_CpPtr<T>. It provides a simple wrapper around a pointer to type T (a T*) that "does the right thing" when copied from one PP_CpPtr<T> to another. The type T MUST be a user-defined type, not an intrinsic type. Given this restriction, we can supply an operator->().

This is a convenience class for ParmParse and will not be in any way supported by anyone at ANAG.

PP_CpClassPtr ()
The default constructor. The wrapped pointer is null.

PP_CpClassPtr (T* rhs)
Construct a PP_CpPtr<T> setting the wrapped pointer to rhs.

PP_CpClassPtr (const PP_CpClassPtr<T>& rhs)
The copy constructor. If the pointer wrapped by rhs is null, the wrapped pointer is null here as well. Otherwise, the contained pointer here is set to a new'd copy of that wrapped by rhs, with the two pointed-to values being identical. This assumes that type T has a well-defined and accessible copy constructor. T must also be a concrete type, not a abstract type.

PP_CpClassPtr<T>& operator= (T* rhs)
Sets the wrapped pointer to rhs. Deletes the previously wrapped pointer.

PP_CpClassPtr<T>& operator= (const PP_CpClassPtr<T>& rhs)
The copy assignment operator. If the pointer wrapped by rhs is null, the wrapped pointer is null here as well. Otherwise, the contained pointer here is set to a new'd copy of that wrapped by rhs, with the two pointed-to values being identical. This assumes that type T has a well-defined and accessible copy constructor. T must also be a concrete type, not a abstract type.

T* operator-> () const
Applies operator-> to the wrapped pointer.
