How can I tell the difference between a server-side ICommandSender and a...

The subject bar is not long enough for my question

 

In CommandBase.execute, the sender argument can be an instance of EntityPlayerMP or DedicatedServer depending on where the command is run. If the command is ran from the server command line, sender is DedicatedServer but if the command is ran from single player chat, sender is also DedicatedServer. How can I discriminate between these two? My command can't be ran from the server cli because the server sends a message to the client to do some rendering that wouldn't be available server-side.

Huh. That's weird, let me check again.

Why did I think that sender in a single player environment is an instance of DedicatedServer? PEBKAC I guess.
