Constructor Detail

IncreaseLanguageLevelFix

public IncreaseLanguageLevelFix(LanguageLevel targetLevel)

Method Detail

getText

public java.lang.String getText()

Description copied from interface: IntentionAction

Returns text to be shown in the list of available actions, if this action is available.

Specified by:

getText in interface IntentionAction

Returns:

the text to show in the intention popup.

See Also:

IntentionAction.isAvailable(Project, Editor, PsiFile)

getName

public java.lang.String getName()

Specified by:

getName in interface QuickFix<ProblemDescriptor>

Returns:

the name of the quick fix.

getFamilyName

public java.lang.String getFamilyName()

Description copied from interface: IntentionAction

Returns the name of the family of intentions. It is used to externalize "auto-show" state of intentions. When the user clicks on a light bulb in intention list, all intentions with the same family name get enabled/disabled. The name is also shown in settings tree.

Specified by:

getFamilyName in interface IntentionAction

Specified by:

getFamilyName in interface QuickFix<ProblemDescriptor>

Returns:

the intention family name.

IntentionManager.registerIntentionAndMetaData(IntentionAction, String...)

applyFix

public void applyFix(Project project,
                     ProblemDescriptor descriptor)

Description copied from interface: QuickFix

Called to apply the fix.

Please call com.intellij.profile.codeInspection.ProjectInspectionProfileManager#fireProfileChanged() if inspection profile is changed as result of fix.

Specified by:

applyFix in interface QuickFix<ProblemDescriptor>

Parameters:

project - Project

descriptor - problem reported by the tool which provided this quick fix action

isAvailable

public boolean isAvailable(Project project,
                           Editor editor,
                           PsiFile file)

Description copied from interface: IntentionAction

Checks whether this intention is available at a caret offset in the file. If this method returns true, a light bulb for this intention is shown.

Specified by:

isAvailable in interface IntentionAction

Parameters:

project - the project in which the availability is checked.

editor - the editor in which the intention will be invoked.

file - the file open in the editor.

Returns:

true if the intention is available, false otherwise.

invoke

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

Description copied from interface: IntentionAction

Called when user invokes intention. This method is called inside command. If IntentionAction.startInWriteAction() returns true, this method is also called inside write action.

Specified by:

invoke in interface IntentionAction

Parameters:

project - the project in which the intention is invoked.

editor - the editor in which the intention is invoked.

file - the file open in the editor.

Throws:

IncorrectOperationException

getElementToMakeWritable

public PsiElement getElementToMakeWritable(PsiFile file)

Description copied from interface: FileModifier

Controls whether this intention/fix is going to modify the current file. If @NotNull, and the current file is read-only, it will be made writable (honoring version control integration) before the intention/fix is invoked.

By default, as a heuristic, returns the same as WriteActionAware.startInWriteAction().

If the action is going to modify multiple files, or the set of the files is unknown in advance, please don't bother overriding this method, return false from WriteActionAware.startInWriteAction(), and call FileModificationService methods in the implementation, and take write actions yourself as needed.

Specified by:

getElementToMakeWritable in interface FileModifier

Parameters:

file - the same file where intention would be invoked (for LocalQuickFix it would be the containing file of ProblemDescriptor.getPsiElement())

startInWriteAction

public boolean startInWriteAction()

Description copied from interface: IntentionAction

Indicate whether this action should be invoked inside write action. Should return false if, e.g., a 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 IntentionAction

Specified by:

startInWriteAction in interface WriteActionAware

Returns:

true if the intention requires a write action, false otherwise.
