[udig-devel] Doubt on the catalog ConnectionFactory extension

[Mauro Bartolomeoli <m.bartolomeoli@xxxxxxxxx>]

I'm developing a plugin to implement a new type of layer for Udig 1.1.x. 
This layer uses a GeoTools DataStore as a source for data, connecting to 
a custom spatial database.
I started "copying" the Postgis plugin, which seems quite similar to the 
one I need to write. The plugin is now correctly rendering data from the 
DataStore, without the implementation of a ConnectionFactory (the 
factory extension has been defined and the related class exists, but I 
didn't write any meaningful code in it). Now my question is: what's the 
purpose of the factory extension? Which features of Udig needs it?

Thanks in advance,
Mauro Bartolomeoli
