C++ Tip: Modification Inside const Function

Introduction There are times where modification inside const member function must be done (for example, to allow for caching or memoization). The mutable keyword and const_cast are well-known in the C++ circles to work around these. The 3rd way is to use a const pointer; we cannot modify the const pointer but we can […]

C++ Tip: Make Your Class Non-Copyable Without Boost

Introduction There are times where an object should never be passed by copy but by reference or pointer. For instance, the class has a data member (like counter or mutex) which should not be duplicated. In this tip, we take a look at 2 techniques which declare the class to be non-copyable without resorting to using […]
