/// Forward iterator
/**
- The iteration is unordered.
- The iterator object is thread-safe: the element pointed by the iterator object is guarded,
- so, the element cannot be reclaimed while the iterator object is alive.
- However, passing an iterator object between threads is dangerous.
-
- @warning Due to concurrent nature of Michael's map it is not guarantee that you can iterate
- all elements in the map: any concurrent deletion can exclude the element
- pointed by the iterator from the map, and your iteration can be terminated
- before end of the map. Therefore, such iteration is more suitable for debugging purpose only.
-
- Remember, each iterator object requires an additional hazard pointer, that may be
- a limited resource for \p GC like \p gc::HP (for \p gc::DHP the count of
- guards is unlimited).
-
- The iterator class supports the following minimalistic interface:
+ The forward iterator for Michael's map has some features:
+ - it has no post-increment operator
+ - to protect the value, the iterator contains a GC-specific guard + another guard is required locally for increment operator.
+ For some GC (like as \p gc::HP), a guard is a limited resource per thread, so an exception (or assertion) "no free guard"
+ may be thrown if the limit of guard count per thread is exceeded.
+ - The iterator cannot be moved across thread boundary because it contains thread-private GC's guard.
+
+ Iterator thread safety depends on type of \p OrderedList:
+ - for \p MichaelKVList and \p LazyKVList: iterator guarantees safety even if you delete the item that iterator points to
+ because that item is guarded by hazard pointer.
+ However, in case of concurrent deleting operations it is no guarantee that you iterate all item in the map.
+ Moreover, a crash is possible when you try to iterate the next element that has been deleted by concurrent thread.
+ Use this iterator on the concurrent container for debugging purpose only.
+ - for \p IterableList: iterator is thread-safe. You may use it freely in concurrent environment.
+
+ The iterator interface:
\code
- struct iterator {
- // Default ctor
+ class iterator {
+ public:
+ // Default constructor
iterator();
- // Copy ctor
- iterator( iterator const& s);
+ // Copy construtor
+ iterator( iterator const& src );
+ // Dereference operator
value_type * operator ->() const;
+
+ // Dereference operator
value_type& operator *() const;
- // Pre-increment
+ // Preincrement operator
iterator& operator ++();
- // Copy assignment
+ // Assignment operator
iterator& operator = (iterator const& src);
+ // Equality operators
bool operator ==(iterator const& i ) const;
bool operator !=(iterator const& i ) const;
