<DD>Returns a view of the contents of this multiset, grouped into <code>Multiset.Entry</code> instances, each providing an element of the multiset and
 the count of that element. This set contains exactly one entry for each

 unspecified.

 <p>The entry set is backed by the same data as the multiset, so any change
 to either is immediately reflected in the other. However, multiset changes
 may or may not be reflected in any <code>Entry</code> instances already
 retrieved from the entry set (this is implementation-dependent).
 Furthermore, implementations are not required to support modifications to
 the entry set at all, and the <code>Entry</code> instances themselves don't
 even have methods for modification. See the specific implementation class
 for more details on how its entry set handles modifications.
