    public abstract class RefactoringWizard
    extends Wizard
    An abstract base implementation of a refactoring wizard. A refactoring wizard differs from a normal wizard in the following characteristics:
    • only pages of type RefactoringWizardPage can be added to a refactoring wizard. Trying to add a different kind of page results in an exception.
    • a refactoring wizard consists of 0 .. n user input pages, one error page to present the outcome of the refactoring's condition checking and one preview page to present a preview of the workspace changes.

    A refactoring wizard is best opened using the RefactoringWizardOpenOperation.

    Clients may extend this class.

        public static final int CHECK_INITIAL_CONDITIONS_ON_OPEN
        Flag (value 1) indicating that the initial condition checking of the refactoring is done when the wizard opens. If not specified it is assumed that the initial condition checking has been done by the client before opening the wizard dialog.

      • WIZARD_BASED_USER_INTERFACE

        public static final int WIZARD_BASED_USER_INTERFACE
        Flag (value 2) indicating that a normal wizard based user interface consisting of a back, next, finish and cancel button should be used to present this refactoring wizard. This flag can't be specified together with the flag DIALOG_BASED_USER_INTERFACE.

        Constant Field Values
      • DIALOG_BASED_USER_INTERFACE

        public static final int DIALOG_BASED_USER_INTERFACE
        Flag (value 4) indicating that a lightweight dialog based user interface should be used to present this refactoring wizard. This user interface consists of a preview, finish and cancel button and the initial size of dialog is based on the first user input page. This flag is only valid if only one user input page is present. Specifying this flag together with more than one input page will result in an exception when adding the user input pages. This flag can't be specified together with the flag WIZARD_BASED_USER_INTERFACE.

      • addPages

        public final void addPages()
        The Wizard implementation of this IWizard method does nothing. Subclasses should extend if extra pages need to be added before the wizard opens. New pages should be added by calling addPage. This method calls the hook method addUserInputPages() to allow subclasses to add specific user input pages.

        addPages in interface IWizard
        Overrides:
        addPages in class Wizard

        Adds a new page to this wizard. The page is inserted at the end of the page list. This method asserts that the pages added to the refactoring wizard are instances of type RefactoringWizardPage.
        Overrides:
        addPage in class Wizard
        Parameters:
        page - the new page
      • addUserInputPages

        protected abstract void addUserInputPages()
        Hook method to add user input pages to this refactoring wizard. Pages added via this call have to be instances of the type UserInputWizardPage. Adding pages of a different kind is not permitted and will result in unexpected behavior.
      • setInitialComputationContext

        public void setInitialComputationContext​(IRunnableContext context)
        Sets the runnable context that will be used to computing refactoring conditions and change while the refactoring dialog is not yet shown. The default is to use the active workbench window.
        Parameters:
        context - a runnable context, or null to re-set the default
