Debugging Memory Errors with Custom Allocators

Listing 1: An extra method for memory access rights has been added to a class that is a potential victim of incorrect memory access

class Victim
{
public:
    // public interface

    // a setter method
    void setSomeData(/* ... */);
    // ...

private:
    // internal data
    // ...

protected:
    // a method for controlling
    // access to internal data

    enum MemoryAccessMode
    { noAccess, readOnly, readWrite };

    // Sets memory access mode for the data members;
    // needs to be overrideable, if derived classes
    // add more data members.
    virtual void setMemoryAccessMode(MemoryAccessMode);
};
