Method Detail

isValidFor

public boolean isValidFor(Editor editor,
                          PsiFile file)

Specified by:

isValidFor in interface LanguageCodeInsightActionHandler

invoke

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

Specified by:

invoke in interface CodeInsightActionHandler

startInWriteAction

public boolean startInWriteAction()

Description copied from interface: WriteActionAware

Indicate whether this action should be invoked inside write action.

Should return false if e.g. modal dialog is shown inside the action. If false is returned the action itself is responsible for starting write action when needed, by calling Application.runWriteAction(Runnable).

Specified by:

startInWriteAction in interface WriteActionAware

Returns:

true if the action requires a write action (default), false otherwise.

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
