public DLIterC<DataT>

ConstDLIterC()

Default constructor.

ConstDLIterC(const DListC<DataT> & nlst)

Constructor.

bool IsValid() const

Is a valid iterator ?

void First()

Goto first item in list.

void Last()

Goto last item in list.

const DListC<DataT> & List() const

Access list we're iterating.

DListC<DataT> Copy() const

Make a copy of this list.

operator bool() const

Is iterator at a valid position ?

bool operator !() const

Is iterator at a invalid position ?

void operator ++(int)

Goto next element.

void operator ++()

Goto next element.

void operator --(int)

Goto previous element.

void operator --()

Goto previous element.

void InsertBef(const DataT & dat)

Insert data before current element.
if at the head of the list (i.e. operator bool() failes.) then add at end.

void InsertAft(const DataT & dat)

Insert data after current element.
if at the head of the list (i.e. operator bool() failes.) then add at begining.

void MoveBef(DLIterC<DataT> & it)

Move the list element indicated by 'it' to before the element in this list.

void MoveAft(DLIterC<DataT> & it)

Move the list element indicated by 'it' to before the element in this list.

void Del()

Remove current element from the list.
This moves the iterator to the previous element. NB. The iterator must be pointing to a valid element.

Because the moves the prevous element it makes it easy to delete elements from a list in a for() loop. e.g. the following will work correctly.

 for(DLIterC it(x);it;it++) 
   if(*it == 2)
     it.Del();
 

void DelMoveNext()

Remove current element from the list.
This moves the iterator to the previous element. NB. The iterator must be pointing to a valid element.

bool operator ==(const DLIterC<DataT> & oth) const

Are these iterators equal ?
True if both iterators point to the same element in the same list. False otherwise.

bool operator !=(const DLIterC<DataT> & oth) const

Are these iterators unequal ?
True if the iterators point to different elements in any lists. False otherwise.

bool IsElm() const

Is iterator at a valid position ?
AMMA compatibility function, use cast to bool instead ie if(iter) {..}

bool IsFirst() const

Returns true if the current element is the first in the list.

bool IsLast() const

Returns true if the current element is the last in the list.

void Next()

Goto next element.

void Prev()

Goto previous element.

void NextCrc()

Goto next element.
If the next element is the head of the list, loop back to the begining of the list.

void PrevCrc()

Goto previous element.
If the next element is the head of the list, go to the begining of the list.

DLIterC<DataT> & RelNth(IntT n)

Move 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.

Returns a reference to this iterator.

DLIterC<DataT> & Nth(IntT 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.

Returns a reference to this iterator.

DataT & Data()

Access data

const DataT & Data() const

Constant access to data.

DataT & operator *()

Access data.

const DataT & operator *() const

Constant access to data.

DataT * operator ->()

Access member function of data..

const DataT * operator ->() const

Constant access to member function of data..

DataT & NextData()

Access data following this element.
The iterator must not be on the last element of the list.

const DataT & NextData() const

Access data following this element.
The iterator must not be on the last element of the list.

DataT & PrevData()

Access data before this element.
The iterator must not be on the first element in the list.

const DataT & PrevData() const

Access data before this element.
The iterator must not be on the first element in the list.

DListC<DataT> Tail()

Clip out the tail of the list.
Return all of the elements after this element in the list.

DListC<DataT> Head()

Clip out the head of the list.
Return all of the elements before this element in the list.

DListC<DataT> InclusiveTail()

Clip out the tail of the list including this element.
Returns this element and the following elements from the list. The interator is left point to the last element in the remaining list.

DListC<DataT> InclusiveHead()

Clip out the head of the list including this element.
Returns this element and the following elements from the list. The interator is left point to the last element in the remaining list.

DListC<DataT> Clip(const DLIterC<DataT> & end)

Clip out section of the list
Returns the elements starting from this one to the element before the end. This iterator is moved the previous element.

NB. It is the user's responsibility to ensure 'end' is an element following this element in the same list.

DLinkDataC<DataT> & DLinkData()

Access as data element.

const DLinkDataC<DataT> & DLinkData() const

Access as data element.

DLinkDataC<DataT> & Extract()

Extract the current element, move the iterator back 1.

DLinkDataC<DataT> & ExtractNext()

Extract the current element, move the iterator to the next element in the list.

ostream & operator <<(ostream & strm,const DListBodyC<DataT> & lst)

BinOStreamC & operator <<(BinOStreamC & strm,const DListBodyC<DataT> & lst)
