Code Generation

One of the most useful code generator is the Generate Application Code function, which, after a new Application subclass has been defined, generates all code that is required for an empty application window, a main menu and some initial template code.
Further application development from this initial code is very easy using the Menu- and UIPainter tools.

Notice, that these code generators never overwrite existing code. To re-generate a method, it is required to remove any existing method before.

• Class Menu - Generate:
  • Access Methods
  • Getter Methods
  • Setter Methods
  • Multi Setter Method

  • Access Methods with Lazy Initialization
  • Access Methods with Change Notification
  • Access Methods for ValueHolder
  • Access Methods for ValueHolder with Change Notification

  • Update Method Template
  • Visitor Method
  • Visitor and Visited Methods
  • Classtype Test Methods

  • Documentation Stubs
  • Initialized Instance Creation
  • Application Code
  • Sharedpool Initialization
  • Required Protocol

• Variable Menu - Generate:
  • Access Methods
  • Getter Methods
  • Setter Methods
  • Multi Setter Method

  • Access Methods with Lazy Initialization
  • Access Methods with Change Notification
  • Access Methods for ValueHolder
  • Access Methods for ValueHolder with Change Notification

• Selector Menu - Generate:
  • SubclassResponsibility in Superclass
  • SubclassResponsibility Here
  • Templates in Subclasses
  • Corresponding Instance Creation
  • Forwarding Method on Instance Side

Attribute Access

Access Methods

Generates getter/setters for the selected instance/class variable(s).
Similar to the corresponding "Abstract Variable Refactoring", but does not rewrite any code which accesses the variable(s).

Getter Methods

Generates getters for the selected instance/class variable(s).

Setter Methods

Generates setters for the selected instance/class variable(s).

Multi Setter Method

Generates a setter method for the selected instance/class variable(s). This method expects multiple arguments and writes all instances variables (useful for initializers).

Access Methods with Lazy Initialization

Generates getter/setters for the selected instance/class variable(s).
The getter method performs lazy initialization of the intance variable

Access Methods with Change Notification

Generates getter/setters for the selected instance/class variable(s).
The setter method sends out a change notification to observers (i.e. dependents).

Access Methods for ValueHolder

Generates getter/setters for the selected instance/class variable(s). The actual value is kept in a valueHolder.

Access Methods for ValueHolder with Change Notification

Like above. In addition, the setter sends out a change notification to observers (i.e. dependents)..

Common Patterns

Update Method Template

Generates an empty #update:with:from: method (Observer entry).

Visitor Method

Generates a visitor entry method (part of visitor pattern).

Visitor and Visited Methods

Generates both visitor and visited methods (full visitor pattern).

Classtype Test Methods

Generates #isXXX classType test methods in the selected class and all subclasses. (like isString.)

Class Code

Documentation Stubs

Generates empty documentation methods on the class-side.

Application Code

Generates initial window- and menu- specification methods and also dummy hooks for an application. This menu item is enabled if the selected class is a subclass of ApplicationModel.

Initialized Instance Creation

Generates a dummy #initialize method and a #new-method on the class side, which invokes this initializer.

Corresponding Instance Creation

Generates an instance creation method on the class side, named the same as the selected method, which invokes the selected method.

Sharedpool Initialization

Generates code to initialize the pool's class-variables.

Framework Building / Filling

Required Protocol

Generates dummy methods for all those selectors which are declared as #subclassResponsibility in a superclass. Useful to help in implementing the required protocol in a whiteBox framework.

SubclassResponsibility in Superclass

Generates a trapping #subclassResponsibility method in the superclass for the selected method's selector.

SubclassResponsibility Here

Generates a trapping #subclassResponsibility method.

Templates in Subclasses

Generates dummy template methods for the selected method's selector in all subclasses.

Forwarding Method on Instance Side

Generates an instance method, which forwards the selected message to the class side. The forwarding method takes the same arguments as the selected class method.
(See also "Move to Class with Forwarder", found in the selector menu, which moves a method to another class with forwarding).
