DESCRIPTION

       The QPtrDictIterator class provides an iterator for
       QPtrDict collections.

       QPtrDictIterator is implemented as a template class.
       Define a template instance QPtrDictIterator<X> to create a
       dictionary iterator that operates on QPtrDict<X>
       (dictionary of X*).

       Example:

           #include <qptrdict.h>
           #include <stdio.h>
           void main()
           {
               int *a = new int[12];
               int *b = new int[10];
               int *c = new int[18];
               int *d = new int[13];
               QPtrDict<char> dict;               // maps void* -> char*
               dict.insert( a, "a is int[12]" );  // describe pointers
               dict.insert( b, "b is int[10]" );
               dict.insert( c, "c is int[18]" );
               QPtrDictIterator<char> it( dict ); // iterator for dict
               while ( it.current() ) {
                   printf( "%x -> %s\n", it.currentKey(), it.current() );
                   ++it;
               }
           }

       Program output:

               804a788 -> a is int[12]

               804a7c0 -> b is int[10]

       Note that the traversal order is arbitrary, you are not
       guaranteed the order above.

       Multiple iterators may independently traverse the same
       dictionary. A QPtrDict knows about all iterators that are
       operating on the dictionary. When an item is removed from
       the dictionary, QPtrDict update all iterators that are
       referring the removed item to point to the next item in
       the traversing order.

MEMBER FUNCTION DOCUMENTATION


QPtrDictIterator::QPtrDictIterator ( const QPtrDict & dict

       )
       Constructs an iterator for dict. The current iterator item
       is set to point on the first item in the dict.


QPtrDictIterator::~QPtrDictIterator ()

       Destroys the iterator.


QPtrDictIterator::operator type * () const

       Cast operator. Returns a pointer to the current iterator
       item. Same as current().


uint QPtrDictIterator::count () const

       Returns the number of items in the dictionary this
       iterator operates on.

       See also isEmpty().


type * QPtrDictIterator::current () const

       Returns a pointer to the current iterator item.


void * QPtrDictIterator::currentKey () const

       Returns the key for the current iterator item.


bool QPtrDictIterator::isEmpty () const

       Returns TRUE if the dictionary is empty, i.e. count() ==
       0. Returns FALSE otherwise.

       See also count().


type * QPtrDictIterator::operator() ()

       Makes the succeeding item current and returns the original
       current item.

       If the current iterator item was the last item in the
       dictionary or if it was null, null is returned.

       Prefix ++ makes the succeeding item current and returns
       the new current item.

       If the current iterator item was the last item in the
       dictionary or if it was null, null is returned.


type * QPtrDictIterator::operator+= ( uint jump )

       Sets the current item to the item jump positions after the
       current item, and returns a pointer to that item.

       If that item is beyond the last item or if the dictionary
       is empty, it sets the current item to null and returns
       null.


type * QPtrDictIterator::toFirst ()

       Sets the current iterator item to point to the first item
       in the dictionary and returns a pointer to the item.  If
       the dictionary is  empty it sets the current item to null
       and returns null.
