Method Detail

invoke

public void invoke(Project project,
                   PsiElement [] elements,
                   DataContext dataContext)

Description copied from interface: RefactoringActionHandler

Invokes refactoring action from elsewhere (not from editor). Some refactorings do not implement this method.

Specified by:

invoke in interface RefactoringActionHandler

Parameters:

project - the project in which the refactoring is invoked.

elements - list of elements that refactoring should work on. Refactoring-dependent.

dataContext - can be null for some but not all of refactoring action handlers (it is recommended to pass DataManager.getDataContext() instead of null)

invoke

public void invoke(Project project,
                   Editor editor,
                   PsiFile file,
                   DataContext dataContext)

Description copied from interface: RefactoringActionHandler

Invokes refactoring action from editor. The refactoring obtains all data from editor selection.

Specified by:

invoke in interface RefactoringActionHandler

Parameters:

project - the project in which the refactoring is invoked.

editor - editor that refactoring is invoked in

file - file should correspond to editor

dataContext - can be null for some but not all of refactoring action handlers (it is recommended to pass DataManager.getDataContext() instead of null)

selectAndPass

public static void selectAndPass(Project project,
                                 Editor editor,
                                 PsiFile file,
                                 Pass<PsiElement[]> callback)

isAvailableForQuickList

public boolean isAvailableForQuickList(Editor editor,
                                       PsiFile file,
                                       DataContext dataContext)

Description copied from interface: ContextAwareActionHandler

Handlers could provide useful hints when they are actually not available, e.g. 'No methods to implement', 'Selected block should represent ...', 'Caret should be positioned at the name of ...', etc. At the same time, when the action is invoked through refactorings quick list popup, generate popup or in another manner but not through main menu (shortcut or find action are treated the same), it's better to hide the action: it would pollute menu with one more choice but can't do anything.

Specified by:

isAvailableForQuickList in interface ContextAwareActionHandler

Returns:

It's assumed that handler is valid for file. Still should be lightweight, because is invoked from action update. false - if action won't proceed

getElements

public static PsiElement[] getElements(Project project,
                                       Editor editor,
                                       PsiFile file)

invokeOnElements

public static void invokeOnElements(Project project,
                                    Editor editor,
                                    PsiFile file,
                                    PsiElement [] elements)

extractMethod

public static void extractMethod(Project project,
                                 ExtractMethodProcessor processor)

                                         Project project)

                                                  boolean openEditor)
