I thought of having multiple directives: one for single-state icons; one for dual-state icons; and so on -- but then how do I tie them all back to a single controller? I guess the obvious question is: why do I think I need only a single controller? Things would be simpler if I mad tuples: directive+controller+service=singleStateActionIcon; directive+controller+service=dualStateActionIcon; and so on...
I like the idea of a container for these icons, that would let me manage them as a group, perhaps there will be a set of icons that don't live in a table cell. These icons will be the users interface to initiate actions -- there are lots of different actions to take depending on what kind of entity is being listed in the table. I'm using a service only to encapsulate the data structures and business logic that will represent the state of and action triggered by the icons in the row, which one should be shown with what tooltip, and what actions are taken when the icons are clicked and so on - there will be no server interaction directing the icon set after initial creation. I've seen many posts on wrapping business related logic in services to keep it out of the presentation layer (controllers, directives, etc) . If an icon click causes a server action I'll be dealing with that through a resource via logic in some higher-level service elsewhere.
