[udig-devel] IService has the same tradeoffs

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

IService and friends has the same set of Tradeoffs, I don't need the 
answer for this one today.

IService has the same arangement - with one interesting wrinkle. The 
IServiceInfo has a getIcon() method.

Using the same recomendations as before - I am going to consider any 
IServiceInfo as having the possibility of blocking.

I have added ISharedImages.getImageDescriptor( IService ) and 
ISharedImages.getImageDescriptor( IGeoResource ) as the non blocking 
Icon creation just based on type.

That leaves IServiceInfo.getIcon() free to block while talking to 
locating the icon specified in the GetCapabilities file, or on disk.
