Ref Class
operator=()
ptr()
Parameters
ref
The Ref object of the object to be compared.
Assigns the ref or the object to a ref. For the first case, the refs are assigned and for
the second case, the ref is constructed from the object and then assigned.
Syntax
There are variants of syntax:
Ref& operator=(const Ref &src);
Ref& operator=(const T *obj);
Parameters
src
The source Ref object to be assigned.
obj
The source object pointer whose Ref object is to be assigned.
This operator dereferences the Ref and pins/fetches the object if necessary. This
might result in prefetching a graph of objects if prefetch attributes of the Ref are set.
Syntax
There are variants of syntax:
T * ptr();
const T * ptr() const;
