RWTValHashMultiSetIterator provides an iterator interface to the C++ Standard Library-based collection represented by RWTValHashMultiSet. (An STL iterator interface is provided through RWTValHashMultiSet::iterator.)
Iteration over an RWTValHashMultiSet 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 defined to be equivalent by the equivalence object, EQ
, will be 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 hashed multiset 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 value currently referenced by self.
|
inline |
Advances self to the next element. Returns false
if the iterator has advanced past the last element in the container, otherwise returns true
.
|
inline |
Advances self to the next element. If the iterator has been reset or just created, self now references the first element. If, before iteration, self referenced the last value in the multiset, self now references an undefined value and the operator returns false
, Otherwise, it returns true
.
|
inline |
Resets the iterator so that after being advanced it will reference the first element of the collection.
