Convert Anonymous Inner Class to Nested Class Refactoring Specification

$ (see full
CVS
history)
Refactoring feature that allows to convert an anonymous inner class
to a nested class.
Implementation of this refactoring is tracked in issue
56437.
Pre-Conditions
- Anonymous class residing in an editable source code base must be
selected.
Pre-Checks
No specific checks.
Parameters
- Name of the nested class to be created.
- Modifiers (accessibility, static/instance class) the nested class
should be created with. If the anonymous class resides in a static
context, the nested class is forced to be static.
Fast Parameters Check
- Error: No anonymous class selected to convert to nested class.
Parameters Check
- Error: The selected nested class name clashes, there is already a
nested class of this name.
- Warning: The nested class will hide nested class in a
supertype, i.e.
there is already an accessible nested class of the same name in a
supertype.
Changes To Be Made
- Create the nested class in the outer class of the anonymous
class. The class contains the same members and the anonymous class. In
addition a proper constructor is required to be added whenever the
anonymous class is instantiated by non-default constructor. In this
case, the added constructor has the same number of parameters as the
used constructor and in its body, the instatiation is delegated to
supertype.
- Replace the instantiation of the anonymous class (including
definition of the class) by an instantiation of the nested class.
Checks During Changes Preparation
No specific checks.
Refactoring UI
Menu item:
Convert Anonymous to Nested...
Action title:
Convert Anonymous to Nested - Name of Super type (e.g. Runnable)
The panel should display a text field for editing the name of the
nested class. The name is preset to be of the form "MyClassName", where
"ClassName" is the name of the super type which is extended by the
anonymous class. The remaining part of the panel should contain a combo
box for selecting accessibility modifier ("private" should be default)
and a checkbox for selecting whether the nested class should be static
or not (the default value corresponds to the context the anonymous
class is defined in and it cannot be changed if the context is static).
