Comments:
The class 'BaseBodyConstDLIterC' is a representation of iterator on a body of a constant double-linked list. Therefore this iterator cannot change the content of the list. Iterator is connected with a list. If the list is empty, the iterator points to the head of the list. The result of positioning of an iterator need not to be a proper element. To avoid pointing to the head of the list the head skipping moving operators NextCrc() and/or PrevCrc() must be used.

const DataC & Data() const

Access to the constant object contained in the list element.

const DataC & operator*() const

Access to the constant object contained in the list element.

const DataC * operator->() const

Access to the constant object contained in the list element.

const DataC & NextData() const

Access to the constant object contained in the list element.

const DataC & PrevData() const

Access to the constant object contained in the list element.

const DataC & NextCrcData() const

Access to the constant object contained in the list element.

const DataC & PrevCrcData() const

Access to the constant object contained in the list element.

const DataC & NextData(int offset) const

Access to the constant object contained in the list element.

const DataC & PrevData(int offset) const

Access to the constant object contained in the list element.

const DataC & NextCrcData(int offset) const

Access to the constant object contained in the list element.

const DataC & PrevCrcData(int offset) const

Access to the constant object contained in the list element.

const BodyDListC<DataC> & List() const

Returns the list whose element is pointed to by this iterator. ------------ Predicates -------------------------------------

BooleanT operator==(const BaseBodyConstDLIterC<DataC> & it) const

Returns TRUE if both iterators point to the same list element.

BooleanT operator!=(const BaseBodyConstDLIterC<DataC> & it) const

Returns TRUE if this iterators points to a different list element than the iterator 'it'.

BooleanT IsFirst() const

Returns TRUE if the pointed element is the first in a list.

BooleanT IsLast() const

Returns TRUE if the pointed element is the last one in a list.

BooleanT IsElm() const

Returns TRUE if the pointed an proper element (not a head) of a list. ----------- Positioning the iterator -----------------------------

BaseBodyConstDLIterC<DataC> & First()

Sets the iterator to point to the first element of the list.

BaseBodyConstDLIterC<DataC> & Last()

Sets the iterator to point to the last element of the list.

BaseBodyConstDLIterC<DataC> & Next()

Moves the iterator to the successor of the element.

void operator++(int)

Moves the iterator to the successor of the element.

BaseBodyConstDLIterC<DataC> & Prev()

Moves the iterator to the predecessor of the element.

BaseBodyConstDLIterC<DataC> & NextCrc()

Moves the iterator to the successor of the element. If the result element is not a proper element of the list the iterator is moved to the first element.

BaseBodyConstDLIterC<DataC> & PrevCrc()

Moves the iterator to the predecessor of the element. If the result element is not a proper element of the list the iterator is moved to the last element.

BaseBodyConstDLIterC<DataC> & Nth(LongIntT n)

Sets to the n-th element of the list. The index 'n' can be negative. The first element of the list has the index 0, the last element has the index -1. It does not skip the head of the list.

BaseBodyConstDLIterC<DataC> & RelNth(LongIntT n)

Moves to the n-th element from the current element. The index 'n' can be positive, zero, or negative. Particularly, the n = 0 means no move, n = 1 means the move to the next element, and n = -1 means the move to the previous element.

LongIntT Index() const

Returns the offset of an element from the first element. Particularly, it returns 0 if the iterator points to the first element, it returns -1 if element is the head of the list, and it returns -2 if the element is not contained in the list. The function does not check counter overflow.

BaseBodyConstDLIterC()

Default constructor. This constructor is provided because of trouble with an array of iterators. The present ANSI C++ does not enable to pass any constructor of array elements different from a defaut constructor. The extension of GNU g++ compiler is not supported by other compiler. The constructor should be used only for such purposes. If this limitation of C++ is removed, the constructor will be obsolete.

BaseBodyConstDLIterC(const BodyDListC<DataC> & list)

Creates an iterator operating on the constant 'list'. The iterator will point to the first element if there is any, otherwise to the head of the list.

BaseBodyConstDLIterC(const BaseBodyConstDLIterC<DataC> & iter)

Copy constructor.

const BaseBodyConstDLIterC<DataC> & operator=(const BaseBodyConstDLIterC<DataC> & it)

Assingment. This iterator will point to the same list element as the iterator 'it'.

const BaseBodyConstDLIterC<DataC> & DLIter() const

Self-identification. The function returns this object.

const BaseBodyConstDLIterC<DataC> & InsBef(const DataC & data)

Inserts the new element containing 'data' before the element pointed to by this iterator. This iterator is returned.

const BaseBodyConstDLIterC<DataC> & InsAft(const DataC & data)

Inserts the new element containing 'data' after the element pointed to by this iterator. This iterator is returned.

const BaseBodyConstDLIterC<DataC> & MoveBef(BaseBodyConstDLIterC<DataC> & iter)

The element pointed to by 'iter' is moved before the element pointed to by this iterator. This iterator will point to the same element as before, the iterator 'iter' will point to the previous element in the original list.

const BaseBodyConstDLIterC<DataC> & MoveAft(BaseBodyConstDLIterC<DataC> & iter)

The element pointed to by 'iter' is moved after the element pointed to by this iterator. This iterator will point to the same element as before, the iterator 'iter' will point to the previous element in the original list.

const BaseBodyConstDLIterC<DataC> & MoveBef(BodyDListC<DataC> & list)

All elements of the 'list' are moved before the element pointed to by this iterator. The 'list' will be empty after this operation.

const BaseBodyConstDLIterC<DataC> & MoveAft(BodyDListC<DataC> & list)

All elements of the 'list' are moved before the element pointed to by this iterator. The 'list' will be empty after this operation.

const BaseBodyConstDLIterC<DataC> & DelMoveNext()

Deletes the element pointed to by this iterator and moves iterator to the next element.

const BaseBodyConstDLIterC<DataC> & Del()

Deletes the element pointed to by this iterator and moves iterator to the previous element.

BooleanT IsValid() const

Returns TRUE if the iterator was not constructed by the default constructor.
