What is this code?

[authgeek]

I'm looking at "the elements" sample code and I can't find out what this one syntax peculiarity is called. It's also quite difficult to search for.

@interface ElementsTableViewController : UIViewController <UITableViewDelegate> {
	UITableView *theTableView;
	id<ElementsDataSource,UITableViewDataSource> dataSource;	
}

What is the id<*protocol*,*protocol*> thing called? Protocols wrapped in an object?

An object that conforms to those protocols.
So the object you assign as 'dataSource' would have to conform to the ElementsDataSource and UITableViewDataSource protocols.

Thanks refreshe. For some reason I had convinced myself that I couldn't put just one protocol in the angle brackets yesterday. It seems to be working fine today with just one protocol.
