keySet
public ReferenceSortedSet<K> keySet()
- Returns a type-specific-sorted-set view of the keys of this map.
The view is backed by the sorted set returned by 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.
