Re: How to use a comparator?
Hi Neil,
Since the application is running in a client-server environment returning a
TreeSet may raise some issues. For example, as I understand the scenario
that you describe, the TreeSet object will exist on the client and changes
to the set (i.e. set membership) will not be reflected on the server.
Perhaps if you could share something about the requirements that led to your
design decision to return a TreeSet the issues can be resolved more readily.
What is the cardinality of the sets? Will the sets be updated? Will set
member attributes involved in the sorting be updated? How will the set be
used? e.g. Values are displayed and members selected in a GUI.
cheers,
don
