Class MemoryManager: allocates/deallocates memory for objects of a fixed size (the size is a parameter to the constructor). The actual memory is allocated in big chunks, which (at the moment) are never released back. However, the deallocated blocks are later reused.

Typical use of this class is to create MemoryManager* mm = new MemoryManager(sizeof(YourClass)); where YourClass has operators new and delete redefined: void* YourClass::operator new(size_t, MemoryManager* mm) { return mm->newData(); } void YourClass::delete(void*) { } // do not deallocate memory here Then, create objects with obj = new(mm) YourClass(), and destroy them with delete obj; mm->deleteData(obj);
