[SAGA-RG] Java binding: object factories

[Thilo Kielmann]

All,

from this week's meeting on the Java language binding, there is one issue
left over that (to me) sounds like a matter of taste...

For all object factories, we have two flavors, one with an explicit
Session parameter, and one with an implicit (default) Session.

Example:

with the implicit default Session:

File file = FileFactory.createFile(....);


for the explicit Session parameters, there are two proposals:

(a) have the create* methods in the factory classes, resulting in
    two create* methods each, with slightly different signature 
    (Session parameter or not)

example:

File file = FileFactory.createFile(session, ....);

(b) make the Session class also a factory and add all the create*
    methods there.

example:

File file = session.createFile(....);


None of the people I've asked so far seems to have a strong opinion on
this. Personally, I have a slight bias towards (a) as it seems to be
conceptionally simpler. (objects are always created by the factories...)
Also, that's as it is in the current language binding.


I hereby suggest that we keep it "as is" unless somebody can convince us
of the superiority of option (b). (Of course, we will change once convinced ;-)



Regards,


Thilo
