Although all interface methods implemented by a class selected in the Class List of the Class Browser are displayed in the Methods List of the Class Browser, you can display the implemented methods grouped by the interface or interfaces in which they are defined.
This can be useful if your class contains many methods and implements a number of interfaces, particularly when the same implemented method can be defined in one or more interfaces.
By default, implemented interface methods are not grouped by interface.
To group implemented methods into the interfaces in which they are defined
Select the Show Interface Method Mappings command from the View menu.
The Methods List then displays all implemented methods and methods defined in a selected class, followed by each interface name and their implemented methods. A check mark (✓) is displayed at the left of the command in the View menu to indicate that interface methods mappings are shown.
The following diagram shows the implemented methods listed below the interface or interfaces in which they are defined.
For details about implementing an interface for a class, see "Implementing an Interface", later in this chapter.
