IJoinInfoCollection - does this exist?

[EdwardBlair]

Hi -

I was looking for a way to get the classes joined to a feature layer in ArcMap.  A Google search returned a description of an IJoinInfoCollection interface that is exposed on a feature layer.   This looked perfect!   But when I go look for the thing in VS, or really anywhere else, I don't see any evidence of this interface.

Is Google AI just making up stuff?

Any guidance would be much appreciated.

Thx,

Ed
