RWTValHashMultiMapIterator provides an iterator interface to the C++ Standard Library-based collection represented by RWTValHashMultiMap. (An STL iterator interface is provided through RWTValHashMultiMap::iterator.)
Iteration over an RWTValHashMultiMap is pseudorandom and dependent on the capacity of the underlying hash table and the hash function being used. The only usable relationship between consecutive elements is that elements which are defined to be equivalent by the equivalence object, EQ
, will remain adjacent.
The current item referenced by this iterator is undefined after construction or after a call to reset(). The iterator becomes valid after being advanced with either a pre-increment or operator()().
For both operator++() and operator()(), iterating past the last element returns a value equivalent to boolean false
. Continued increments return a value equivalent to false
until reset() is called.
The value
type must have operator==
defined. This requirement is imposed by the C++ Standard Library.
Program Output:
|
inline |
Creates an iterator for the hash multimap h. The iterator begins in an undefined state and must be advanced before the first element is accessible.
|
inline |
Returns a pointer to the collection being iterated over.
|
inline |
Returns the key portion of the association currently referenced by self.
|
inline |
Advances self to the next element, dereferences the resulting iterator, and returns false
if the iterator has advanced past the last item in the container; otherwise returns true
.
|
inline |
Advances self to the next element. If the iterator has been reset or just created, self will now reference the first element. If, before iteration, self referenced the last association in the multimap, self will now reference an undefined value and false
is returned. Otherwise, returns true
.
|
inline |
Resets the iterator so that after being advanced, it will reference the first element of the collection.
|
inline |
Resets the iterator so that after being advanced, it will reference the first element of the collection h.
|
inline |
Returns the value portion of the association referenced by self.
