Обсуждение: C++ and Postgis

Hi All,

First off sorry for cross-posting. I'm hoping for a bigger audience... :]

As for my question:

How does one deal with Postgis geom fields in C++ ?
Google hasn't offered much help so far.

I know I can make a "SELECT astext(my_geom) FROM my_table" and after
parsing the resulting text.
This seems a bit awkward and time-consuming...

Is there a better way to deal with it?

Already thankful for any ideas,
BR,
Pedro.

perhaps
http://postgis.refractions.net/documentation/manual-1.4/ST_AsBinary.html ?

anytime you see a codebase filled with a plethora of function pointers, LockObject and miles of code to achieve simple keyword scope (public/protected/private) then you know the product is ready to be rewritten to OO Language
My suggestion would be Java (so we could use maven for version specific build)
also because I havent seen  anything from C++ that comes close to version specific builds
Also with the Maven-nar-plugin you can incorporate native binaries if you decide for a C++ refactor..

I guess what I'm saying if you're going to bite the bullet to rewrite to C++ why not just take the extra step
to rewrite to Java..yes it doesnt support multiple inheritance of classes but you *can implement multiple interfaces*
