Coding Rules

Name	Checked	Synopsis
OAL#001		Only customize the memory management for a class if memory management is an unacceptably large part of the allocation and deallocation of free store objects of that class
OAL#002		If you overload operator delete, it shall be prepared to accept a null pointer
OAL#003		If you overload operator new for a class, you should have a corresponding operator delete
OAL#004		In case allocated memory has to be deallocated later by someone else, use a unique_ptr with move semantics
OAL#005		Assign a new value to a pointer that points to deallocated memory
OAL#006		delete shall be used only with new
OAL#007		Don't mix new and delete for array and non-array types
OAL#008		Do not use "delete" to delete raw pointers inside smart pointers
OAL#009		Do not overload the global operator new or the global operator delete
OAL#010		Do not overload the new and/or delete operators
OAL#011		Use smart pointers for memory management
OAL#012		Don't use auto_ptr, use unique_ptr instead
OAL#013		Use std::make_shared instead of constructing a shared_ptr from a raw pointer
OAL#015		Use nullptr instead of 0 or NULL for pointers
OAL#017		Use smart pointers from the standard library
OAL#018		Don't forget to give scoped variables a name
R.22		Use make_shared() to make shared_ptrs
R.33		Take a unique_ptr<widget>& parameter to express that a function reseats the widget
