Member Access

 

For the latest documentation on Visual Studio 2017 RC, see Visual Studio 2017 RC Documentation.

Class member access can be controlled by overloading the member access operator (–>). This operator is considered a unary operator in this usage, and the overloaded operator function must be a class member function. Therefore, the declaration for such a function is:

  
class-type *operator–>()  

where class-type is the name of the class to which this operator belongs. The member access operator function must be a nonstatic member function.

This operator is used (often in conjunction with the pointer-dereference operator) to implement "smart pointers" that validate pointers prior to dereference or count usage.

The . member access operator cannot be overloaded.
