class TCollection_BasicMap;
//! This class provides basic services for the
//! iterators on Maps. The iterators are inherited
//! from this one.
//!
//! The iterator contains an array of pointers
//! (buckets). Each bucket is a pointer on a node. A
//! node contains a pointer on the next node.
//!
//! This class provides also basic services for the
//! implementation of Maps.
//! A map iterator provides a step by step exploration of all
//! entries of a map. After initialization of a concrete derived
//! iterator, use in a loop:
//! - the function More to know if there is a current entry for
//! the iterator in the map,
//! - then the functions which read data on an entry of the
//! map (these functions are provided by each type of map),
//! - then the function Next to set the iterator to the next entry of the map.
//! Warning
//! - A map is a non-ordered data structure. The order in
//! which entries of a map are explored by the iterator
//! depends on its contents, and change when the map is edited.
//! - It is not recommended to modify the contents of a map
//! during iteration: the result is unpredictable.
