org.locationtech.udig.catalog.ui.UDIGConnectionFactory.canProcess()

Determines if the connection factory is capable of providing some connection information based on the context object.

Default implementation simply checks if createConnectionParameters and createConnectionURL are non null (since if either work chances are we "canProcess" the context).

Context is often a workbench selection, or a Drag and Drop content such as a URL or File. Reviewing existing implementations the following are popular contents types to converter:

URL
File - usually by file.toURI().toURL()
IResource - usually by resource.toID().toURL()

You may find it handy to refer to your ServiceExtention to see if it can use a URL produced from the provided context. @param object The object to be "processed" or "adapted" into connection information. @return True if the info can be returned based on the context, Default implementation checksif connection parameters or a url can be produced.
