All, the (my) aim of the current discussion is to separate SAGA-related issues from language-specific issues. SAGA-related issues belong to the SAGA spec, the others to specific language-bindings docs. In this context, I am concerned about sections 1.3.6 Object State 1.3.7 Life Time Management 1.3.8 Freeing of Resources and Garbage Collection about 1.3.6: it is not clear (to me ;-) why prev. error condition and callbacks MUST NOT get copied can anybody give a motivation for this, please? (and include it in the document) about 1.3.7.: as I wrote earlier, this should simply become:
The SAGA specification does NOT address issues of object life cycle and memory management at all. It is subject to the language bindings of SAGA to define this in a way that suits the respective programming languages.
about 1.3.8: I am worried bout the last sentence. Please make a link to section 1.5 Otherwise, I am afraid, this might open the door to "weakly compliant" implementations. Thilo -- Thilo Kielmann http://www.cs.vu.nl/~kielmann/
