Implementing Binary Operators in C++ - Tutorial
|
In principle, implementing binary operators such as
operator=
and
operator==
is fairly easy for simple types, but is amazingly
demanding for a class hierarchy of types. In this tutorial we will look
into the complexities and will discuss solutions. The core of the problem
stems from the fact, that objects in a class hierarchy have something in
common, namely their base class part. For this reason, it makes sense
to consider mixed-type operations where objects of different types from
the same class hierarchy are assigned to each other or compared to each
other. Does it make sense to allow mixed-type operations, and if
so, how can they be implemented correctly? |
