RWTValHashDictionaryIterator(3C++) RWTValHashDictionaryIterator(3C++)
Name
RWTValHashDictionaryIterator<K,V> - Rogue Wave library class
Synopsis
#include <rw/tvhdict.h>
unsigned hashFun(const K&);
RWTValHashDictionary<K,V> dictionary(hashFun);
RWTValHashDictonaryIterator<K,V> iterator(dictionary);
Please Note!
If you do not have the Standard C++ Library, use the interface described
here. Otherwise, use the interface to RWTValHashMapIterator described in
the Class Reference.
Description
Iterator for class RWTValHashDictionary<K,V>, allowing sequential access
to all keys and values of a parameterized hash dictionary. Elements are
not accessed in any particular order. Like all Rogue Wave iterators, the
"current item" is undefined immediately after construction -- you must
define it by using operator() or some other (valid) operation. Once the
iterator has advanced beyond the end of the collection it is no longer
valid -- continuing to use it will bring undefined results.

Public Constructor
RWTValHashDictionaryIterator(RWTValHashDictionary& c);
Constructs an iterator to be used with the dictionary c.
Public Operators
RWBoolean
operator++();
Advances the iterator one position. Returns TRUE if the new position is
valid, FALSE otherwise.
RWBoolean
operator()();

RWTValHashDictionaryIterator(3C++) RWTValHashDictionaryIterator(3C++)
Advances the iterator one position. Returns TRUE if the new position is
valid, FALSE otherwise.
Public Member Functions
RWTValHashDictionary*
container() const;
Returns a pointer to the collection over which this iterator is
iterating.
K
key() const;
Returns the key at the iterator's current position. The results are
undefined if the iterator is no longer valid.
void
reset();
Resets the iterator to the state it had immediately after construction.
void
reset(RWTValHashDictionary& c);
Resets the iterator to iterate over the collection c.
V
value() const;
Returns the value at the iterator's current position. The results are
undefined if the iterator is no longer valid.
