ConnectorFactory always return nullpointer #48

Closed ridoo closed 9 years ago

ridoo commented 10 years ago

Why the method registerCatalogExplorers always return a null pointer?

Better: make it void.

When searching for usage references, there are no actual callers of that method. If this method is obsolete, delete it.

ridoo commented 10 years ago

Also ConnectorFactory has a static _explorer vector member containing catalogexplorers. This seems odd, as CatalogExplorer also contains catalog explorers

Here is the magic done: create and register via macro

For GDAL, see explorer declaration and registration.

Eehm, though this is a trick. It is a fairly wellknown trick in the c++ world. whole libraries are built on top of it ( MFC from MS for example).
