Tools.h++ Class Reference

Once the iterator has advanced beyond the end of the collection it is no longer valid -- continuing to use
it will bring undefined results.
Persistence
None
Public Constructor
RWTPtrHashDictionaryIterator(RWTPtrHashDictionary& c);
Constructs an iterator to be used with the dictionary c.
Public Operators
RWBoolean
operator++();
Advances the iterator to the next key-value pair and returns TRUE. When the end of the
collection is reached, returns FALSE and the position of the iterator will be undefined.
K*
operator()();
Advances the iterator to the next key-value pair and returns a pointer to the key. When the end of
the collection is reached, returns nil and the position of the iterator will be undefined. Use
member function value() to recover the dictionary value.
Public Member Functions
RWTPtrHashDictionary*
container() const;
Returns a pointer to the collection over which this iterator is iterating.
K*
key() const;
Returns a pointer to 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iterator is no longer valid.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(RWTPtrHashDictionary& c);
Resets the iterator to iterate over the collection c.
V*
value() const;
Returns a pointer to the value at the iterator's current position. The results are undefined if the
