Click the Precedence tag to examine information about the precedence list of the current class. The precedence view shown in Displaying precedence information in the Class Browser appears.
The precedence list is used to generate the method combinations for a class, and thus can be used to tell you which method applies in a given case.
See The Generic Function Browser for details on examining information about methods.
Figure 8.12 Displaying precedence information in the Class Browser
The areas available are described below.
As with all other views in the Class Browser, the current class is printed in this area. See Class box for full details of its use.
The Filter box lets you restrict the information displayed in the list of precedences. See Filtering information for a description of how to use the Filter box in any tool, and Filtering slot information for an example of how to use it in the Class Browser.
This gives the same class description available in the superclasses, subclasses, and hierarchy views. See Description list for details.
You can operate on any number of selected items in the list of precedences using the commands in the Classes menu. If no items are selected, then the current class is operated on by the commands in this submenu. The standard actions commands described in Performing operations on selected objects are available in this submenu.
Note: If more than one item is selected, and the command chosen from the Classes menu invokes a tool which can only display one item at a time, then the extra items are added to the History > Items submenu of the tool, so that you can easily display them.
