DESCRIPTION

CNDLObject is a node in the CNDLList doubly linked list. In addition to the base class it contains a pointer to the previous node.

Constructors:

CNDLObject();

CNDLObject(CNParam *param);

CNDLObject(CNObject *obj);

Initializes CNDLObject and optionally sets a referenced object.

CNDLObjects have a private destructor and can therefore only be allocated on the heap. Furthermore CNDLObjects cannot be copied, no copy constructor is supplied; an attempt do so results in a runtime error.

In addition to the member functions required by CNCL and to the functions declared at CNSLObject, CNDLObject provides:

CNDLObject *prev(CNDLObject *p);

CNDLObject *prev();

CNDLObject *set_prev(CNDLObject *p);

CNDLObject *get_prev();

Gets/sets the pointer to the previous node. It returns the current pointer.
