13 The Generic Function Browser

13.2 Examining information about method combinations

The method combinations view of the generic function browser lets you examine information about the method combinations of the current generic function, as well as the signatures of the methods defined on the current generic function.

Method combinations show you the order in which methods defined on a generic function are called. 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 choosing View > Method Combinations. The generic function browser appears as shown in Figure 13.2 below.
