Components and interfaces

[Roggan]

Im reading an UML book right now , and according to the book all components realizes an interface of some kind.

im all ok with that when it comes to things like dll/exe files.

but according to the book , a source code file is also a component (with a different steriotype)

what interface does that expose?
or should i just think of it as an made up interface with operations such as "edit","save","open" ?

Think simple. The interface for DLLs might be some operations, for EXE this is likely a user interface (or batch functionality). Your source code will likely implement some functionality in the same way. So that should be the realized interface.
