some suggestions to the C++ interface

Hi folks
while writing the Python bindings I recognized that some of the
objects in CDMA share more or less the same purpose but show a quite
different interface. Attached to this mail you find some suggestions
how to simplify and unify the interfaces of some of the CDMA types.
The idea is to make them as similar and small as possible. Many of the
tasks performed no by class methods can be done by generic function
templates (yes functions are perfectly ok in C++) which would decouple
the algorithm from the internal implementation of a type (an thus,
surprisingly strengthen the object oriented approach by means of
functions ;)). Reducing the size of the interfaces would make it
easier to write engines and most probably also plugins.

There is also an ISliceVector class included in the zip archive. Have
a look on this. It is a decorator for IDataItemPtr allowing simple
iterations over slices.

regards
Eugen

PS: hope to hear some comments from you.

Hi all,

I've just committed some changes in cdma core library. It concerns functionnalities already implemented in the Java port:
- synonyms mechanism
- plugion configuration mechanism (mainly a automatic detection system of keywords mapping document for a given dataset)

I also taken in account some of your suggestions Eugen (see svn logs). It concerns especially those concerning data access in IDataItem and IAttribute interfaces.

Regards,

Stephane
