{@inheritDoc}

The view is backed by the sorted set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Returns:a sorted set view of the keys of this map; it may be safely cast to a type-specific interface.

A wrapper exhibiting a map iterator as an iterator on keys.

To provide an iterator on keys, just create an instance of this class using the corresponding iterator on entries.
