*
* <P>The view is backed by the set returned by {@link #entrySet()}. Note that
* <em>no attempt is made at caching the result of this method</em>, 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.
*
* @return a set view of the keys of this map; it may be safely cast to a type-specific interface.
