The method combinations view lets you examine information about the combined methods of the current generic function. On supplying a signature to the Generic Function Browser, the combined methods of the generic function are displayed together with the arguments that match that method combination point.
Method combinations show you the calling order of methods. They use the class precedence lists of the classes on which the methods of a generic function operate. Being able to view these combinations gives you a simple way of seeing how before, after, and around methods are used in a particular generic function.
You can display this view by clicking the Method Combinations tab. The method combinations view is shown in Generic function browser displaying method combinations below.
