Subject [jira] Commented: (COMPRESS-61) ArchiveStreamFactory could have static methods as well
Date Sat, 28 Mar 2009 10:19:50 GMT


Torsten Curdt commented on COMPRESS-61:

Static singleton's are the "old school" way of doing things. Statics usually cause more problems
that they help. If someone is concerned about object creations he can cache the factories
himself. But usually modern JVMs have become so efficient in handling object creations (especially
if it's a light weight object like this) that I consider it a design mistake to have a static
accessor as part of the API.

> ArchiveStreamFactory currently has to be instantiated in order to use it.
> The methods have to be instance methods in order for subclasses to override them, but
until that is done (will it ever be done?) it seems a bit unnecessary to create an instance
of the class.
> Perhaps there could be a private static instance of the class that could be used with
public static methods?
> The same considerations apply to the other factories.
