The DynamicList class can be regarded as a more advanced version of the C++ standard classes list and vector. It varies its size dynamically:

DynamicList.h

namespace SmallWindows { 
  template <class Type> 
  class DynamicList { 
    public: 

The IfFuncPtr pointer is a function prototype that is used when testing (without changing) a value in the list. It takes a constant value and a void pointer and returns a Boolean value. DoFuncPtr is used when changing a value in the list and takes a (non-constant) value and a void pointer. The void pointers are sent by the calling methods; they hold additional information:

      typedef bool (*IfFuncPtr)(const Type& value, void* voidPtr); 
      typedef void (*DoFuncPtr)(Type& value, void* voidPtr); 

The list can be initialized by, and assigned to, another list. The default constructor creates an empty list, and the destructor deallocates the memory from the list:

      DynamicList(); ...
