Moving a Class Member to a Superclass
See Also
You can use the Pull Up command to move methods and fields to a class that their
current class inherits from.
To initiate the Pull Up operation:
- In the Source Editor or Projects window, select the class that contains members
that you want to move.
- Choose Refactor > Pull Up.
The Pull Up dialog box appears and displays a list of the class's members and
any interfaces that the class implements.
- In the Destination Supertype drop-down list, select the class that you want to move the
members to.
- Select the checkbox for the member or members that you want to move.
If the current class implements any interfaces, there are checkboxes
for these interfaces. If you select a checkbox for an interface, the implements
statement for that interface is moved to the superclass.
- (Optional) If you want to make a method abstract, select the Make Abstract checkbox
for the method. If you select this checkbox, the method will be declared in the
superclass as an abstract method and overridden in the current class. The method
will be assigned the protected access modifier.
- If you click Refactor, the IDE applies
the changes automatically and skips the remaining steps. If you click Preview,
the Refactoring window displays the lines of code that will be changed. Review
the list and clear the checkbox of any code that you do not want changed. If the
class that you are pushing members from has multiple subclasses and you do not
want the members to be pushed to all of them, be sure to clear the checkboxes
for the corresponding subclasses. Click Do Refactoring to apply the selected changes.
