public class CUCorrectionProposal extends ChangeCorrectionProposal implements ICUCorrectionProposal
A proposal for quick fixes and quick assists that work on a single compilation unit. Either atext changeis directly passed in the constructor or methodaddEdits(IDocument, TextEdit)is overridden to provide the text edits that are applied to the document when the proposal is evaluated.The proposal takes care of the preview of the changes as proposal information.

Method Detail
-
addEdits
protected void addEdits(IDocument document, TextEdit editRoot) throws CoreException
Called when theCompilationUnitChangeis initialized. Subclasses can override to add text edits to the root edit of the change. Implementors must not access the proposal, e.g. not callChangeCorrectionProposal.getChange().The default implementation does not add any edits
- Parameters:
document- content of the underlying compilation unit. To be accessed read only.editRoot- The root edit to add all edits to- Throws:
CoreException- can be thrown if adding the edits is failing.
