Matthias Basler a écrit :
The problem is that the AuthorityFactory:getAuthorityCodes() function does not
support any kind of additional hints, like "2D" or "3D" or maybe spatial
restrictions (sth. like "... where 'area' contains 'Germany'").
We would have to figure out an API in order to specify shuch hint. Allowing user to specify a SQL
"WHERE" clause may not be the most appropriate way, since not all factories are SQL backed. We could
consider something like regular expression however.
A suggest to open a JIRA task for those improvements.
Question 1:
Is there already ANY means of telling an authority factory to return 2D
or 3D CRS and CS only? I couldn't find anything related in the code,
but maybe I've overlooked something.
Not at this time.
Question 2:
If not, would you think that it would be possible to add hints to
either this specific "getAuthorityCodes()" method or alternatively to
FactoryFinder.getCRSAuthorityFactory("EPSG", hints);
(The latter one would not require interface changes. It would then
return a factory that produced only 2D or only 3D objects. Why not...)
Yes, we can consider that. As said previously, a first step is to figure out an API (avoiding SQL
instruction if possible).
Martin.
