Method Detail

preCheck
public IStatus preCheck() throws CoreException
Executes some light weight precondition checking. If the returned status is an error then the refactoring can't be executed at all. However, returning an OK status doesn't guarantee that the refactoring can be executed. It may still fail while performing the exhaustive precondition checking done inside the methodsopenDialog
orperform
. The method is mainly used to determine enable/disablement of actions.- Returns:
- the result of the light weight precondition checking.
- Throws:
CoreException
- if an unexpected exception occurs while performing the checking.- See Also:
openDialog(Shell)
,perform(Shell, IRunnableContext)
-
openDialog
public void openDialog(Shell parent) throws CoreException
Opens the refactoring dialog for this rename support.- Parameters:
parent
- a shell used as a parent for the refactoring dialog.- Throws:
CoreException
- if an unexpected exception occurs while opening the dialog.- See Also:
openDialog(Shell, boolean)
-
openDialog
public boolean openDialog(Shell parent, boolean showPreviewOnly) throws CoreException
Opens the refactoring dialog for this rename support.This method has to be called from within the UI thread.
- Parameters:
parent
- a shell used as a parent for the refactoring, preview, or error dialogshowPreviewOnly
- iftrue
, the dialog skips all user input pages and directly shows the preview or error page. Otherwise, shows all pages.- Returns:
true
if the refactoring has been executed successfully,false
if it has been canceled or if an error has happened during initial conditions checking.- Throws:
CoreException
- if an error occurred while executing the operation.- Since:
- 3.3
- See Also:
openDialog(Shell)
-
perform
public void perform(Shell parent, IRunnableContext context) throws InterruptedException, InvocationTargetException
Executes the rename refactoring without showing a dialog to gather additional user input (for example the new name of theIJavaElement
). Only an error dialog is shown (if necessary) to present the result of the refactoring's full precondition checking.The method has to be called from within the UI thread.
- Parameters:
parent
- a shell used as a parent for the error dialog.context
- aIRunnableContext
to execute the operation.- Throws:
InterruptedException
- if the operation has been canceled by the user.InvocationTargetException
- if an error occurred while executing the operation.- See Also:
openDialog(Shell)
,IRunnableContext.run(boolean, boolean, org.eclipse.jface.operation.IRunnableWithProgress)
