An immutable class representing a type-specific singleton sorted map.
This class may be useful to implement your own in case you subclass
a type-specific sorted map.

- Description copied from class:
AbstractReference2ObjectMap
- Returns a type-specific-set view of the keys of this map.
The view is backed by the 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.
