Implementing Methods of an Interface
Introduction
If a class is declared as implementing a certain interface or extending a class with abstract methods, it has to implement the methods of such interface or class. PyCharm creates stubs of the implemented methods, with the default return values for the primitive types, and null values for the objects.
Implementing methods
To implement method of an interface or abstract class, follow these steps:
- Do one of the following:
- On the main menu, choose .
- Press Ctrl+I
- Right-click the editor, choose Generate on the context menu, or press Alt+Insert, and choose Implement methods.
The Select methods to implement dialog appears, displaying the list of classes and interfaces with the methods that can be implemented.
- Select one or more methods to implement. For multiple selection, use Ctrl and Shift keys.
- Click OK.
Changing method body
File template responsible for implementing a method (Implemented method body) accepts predefined template variables from "File Header" e.g. ${USER}
, ${DATE}
, etc.
For example, consider the following file template:
